10 4 System Planning Headend & Distribution System Construction The System Contractor must adhere to both national and local building codes when constructing a Broadband CATV System. This includes, but is not limited to the NEC, NFPA Codes and local building ordinances. Related National Electrical Code (NEC) Articles Article Grounding is one of the largest, most important, and least understood articles in the NEC. As specified in Section 90-1(a), safety is the key element and purpose of the NEC. Proper grounding and bonding is essential for maximum protection of life and property. If over-current protection is considered the first line of defense, grounding could be considered the last line of defense. Article Radio and Television Equipment covers radio and television receiving equipment and amateur radio transmitting and receiving equipment, but not equipment and antennas used for coupling carrier current to power line conductors. Article Community Antenna Television and Radio Distribution Systems covers coaxial cable distribution of radio frequency signals typically employed in community antenna television (CATV) systems. National Fire Protection Agency (NFPA) -

12 6 Current Ratings for Electronic Cables The maximum continuous current rating for an electronic cable is limited by conductor size, number of conductors contained within the cable, maximum temperature rating of the cable, and environmental conditions such as ambient temperature and air flow. To use the current capacity chart, first determine conductor size, temperature rating, and number of conductors from the applicable product description for the cable of interest. Next, find the current value on the chart for the proper temperature rating and conductor size. To calculate the maximum current rating/conductor, multiply the chart value by the appropriate conductor factor. The chart assumes cable is surrounded by still air at an ambient temperature of 25 C. Current values are in RMS Amperes and are valid for copper conductors only. No. of Conductors** Factors NOTE: Current ratings are intended as general guidelines for low power electronic communications and control applications. Current ratings for power applications generally are set by regulatory agencies such as UL, CSA, NEC, and others. ** Do not count shields unless used as a conductor.

13 Headend HVAC Considerations 7 To maximize equipment reliability and life span, the headend room should be temperature controlled. The heat generated by the headend is one of the major contributors to the total amount of BTU s required for heating and cooling. The specified AC wattage dissipation of a headend component directly correlates to the amount of heat it generates. The conversion from watts to the amount of heat generated in BTU s is as follows: Watts x = BTU s/hour With the total BTU s per hour the headend generates along with the buildings room details, a qualified HVAC technician can determine the necessary heating and cooling requirements..

68 62 Digital Content Types SDI SDI (Serial Digital Interface) refers to a family of un-compressed audio/video interfaces standardized by SMPTE (Society of Motion Picture and Television Engineers). HD-SDI (High-Definition Serial Digital Interface) or SMPTE 292M, provides a nominal data rate of Gbit/s. Typical video formats are 720p and 1080i. SD-SDI (Standard-Definition Serial Digital Interface) or SMPTE 259M, provides a nominal data rate of 270 Mbit/s. Typical video format is 480i. Typical interface type is a BNC connector for both HD-SDI and SD-SDI. HDMI (High Definition Multi-media Interface) is an audio/video interface for transmitting uncompressed un-compressed digital data. It was founded in 2002 by Hitachi, Panasonic, Philips, Thomson, Toshiba, Silicon Image, and Sony. The proprietary content encryption scheme used is HDCP (High-bandwidth Digital Content Protection) which is developed by Intel and licensed by the Digital Content Protection, LLC. Nominal data rate is 10.2 Gbits/s and various video formats from 480i to 2160p are supported. The only interface type is the HDMI connector. ASI ASI (Asynchronous Serial Interface) is a streaming data format which often carries an MPEG Transport Stream (MPEG-TS). Unlike the SD-SDI and HD- SDI that are uncompressed, an ASI signal can carry one or multiple SD, HD, or audio programs that are already compressed. Generally, the ASI signal is the final product of video compression, either MPEG2 or MPEG4, and ready for transmission, after necessary conversions, over various types of transmission paths such as coax, fiber, or microwave. For example, for CATV applications the ASI stream is typically converted into QAM. It is converted into 8VSB for broadcast applications. The two transmission formats commonly used by the ASI interface are the 188 byte format and the 204 byte format. The 188 byte format is the more common ASI transport stream. When optional Reed-Solomon error correction data is included the packet can stretch an extra 16 bytes to 204 bytes total. Data rate is variable and dependent on user s application requirements, but the ASI interface of most products support 270 Mbps per DVB-ASI standard.

69 63 DVI DVI (Digital Visual Interface) is a video-only standard designed to provide very high visual quality on digital display devices such as LCD TVs and computers. It was developed to replace the analog VGA (Video Graphics Array) technology. Depending on the DVI type (single or dual link) the data rate is 3.96 and 7.92 Gbits/s. In most CATV applications, a DVI-to-HDMI cable is used to display the DVI signal on a HDMI-compatible TV.

70 64 Digital Closed Captioning For ATSC (digital television) programming, three streams are encoded in the video: two are backward compatible Line 21 captions (CEA-608), and the third is a set of additional caption streams encoded in EIA-708 format. The captioning data is carried in the video user bits of the MPEG-2 bitstream (as specified in ATSC A/53B) and is applicable to both HD and SD. The CEA-708 specification provides for improved captioning compared with CEA-608: Up to 63 services per program (16 announced in PSIP) 8 independently controlled display windows Extended range of characters (i.e. more accented letters and non-latin letters) and fonts (monospaced and proportional spaced, serif and sans-serif) Additional font sizes (viewer-adjustable), backgrounds (including both transparent and translucent backgrounds to optionally replace the big black block), colors and edges More text styles, including edged or drop-shadowed text rather than the letters on a solid background Higher bandwidth, to allow more data per minute of video More language channels, to allow the encoding of more independent caption streams

71 Chroma Sub-Mapping Types 65 4:4:4 YCbCr Each of the three YCbCr components have the same sample rate. This scheme is sometimes used in high-end film scanners and cinematic postproduction. Two SDI connections are normally required to carry this bandwidth: Link A would carry a 4:2:2 signal, Link B a 0:2:2, when combined would make 4:4:4. 4:4:4 RGB (no subsampling) Note that "4:4:4" may instead be referring to RGB (Red, Green, Blue) color space, which implicitly does not have any chroma subsampling at all. 4:2:2 The two chroma components are sampled at half the sample rate of luma: the horizontal chroma resolution is halved. This reduces the bandwidth of an uncompressed video signal by one-third with little to no visual difference. This rate is often used in high-end encoders and video production equipment. 4:2:1 Although this mode is defined, very few firmware or hardware codecs use this sampling mode. Cb horizontal resolution is twice as low as one of Cr (and four times as low as one of Y). This exploits the fact that human eye has less spatial sensitivity to blue/yellow than to red/green. Similar to NTSC, in using lower resolution for blue/yellow than red/green, which in turn has less resolution than luma. 4:1:1 In 4:1:1 chroma subsampling, the horizontal color resolution is quartered, and the bandwidth is halved compared to no chroma subsampling. Originally, 4:1:1 chroma subsampling was not considered to be broadcast quality and was only acceptable for low-end and consumer applications.

72 66 Chroma Sub-Mapping Types Continued 4:2:0 Cb and Cr are each subsampled at a factor of 2 both horizontally and vertically. There are three variants of 4:2:0 schemes, that are sited differently both horizontally and vertically. In MPEG-2, Cb and Cr are co-sited horizontally. Cb and Cr are sited between pixels in the vertical direction (sited interstitially). In JPEG/JFIF, H.261, and MPEG-1, Cb and Cr are sited interstitially, halfway between alternate luma samples. In 4:2:0 DV, Cb and Cr are co-sited in the horizontal direction. In the vertical direction, they are co-sited on alternating lines. The PAL and SECAM color systems are especially well-suited to this kind of data reduction. Most digital video formats corresponding to PAL use 4:2:0 chroma subsampling,

73 Audio Encoding 67 Dolby Digital: Dolby Digital is the name for audio compression technologies developed by Dolby Laboratories. The most elaborate mode in common usage involves five channels for normal-range speakers (20 Hz 20,000 Hz) (right front, center, left front, rear right, rear left) and one channel (20 Hz 120 Hz) for the subwoofer. Dolby Digital (also known as AC-3): AC-3 is a perceptual digital audio coding technique that reduces the amount of data needed to produce high-quality sound. AC-3 is the sound format for digital television ( DTV ), digital versatile discs (DVD s), high definition television ( HDTV ), and digital cable and satellite transmissions. AC-3 is a 5.1 format, which means that it provides five full-bandwidth channels. AC-3 also has a downmixing feature that ensures compatibility with devices that do not support the 5.1 format. Dolby Digital Plus (also known as E-AC-3): E-AC-3 is an enhanced coding system based on the AC-3 codec. It offers increased bitrates (up to Mbit/s), support for more audio channels (up to 13.1), and improved coding techniques to reduce compression artifacts, enabling lower data rates than those supported by AC-3 (e.g. 5.1-channel audio at 256 kbit/s). It is not backward compatible with existing AC-3 hardware. Dolby Digital EX: EX adds an extension to the standard 5.1 channel Dolby Digital codec in the form of matrixed rear channels, creating 6.1 or 7.1 channel output.

74 68 Audio Encoding Continued Dolby Digital Live: Dolby Digital Live (DDL) is a real-time encoding technology for interactive media such as video games. It converts any audio signals on a PC or game console into a 5.1-channel 16-bit/48 khz Dolby Digital format at 640 kbit/s and transports it via a single S/PDIF cable. Dolby Digital Live is available in sound cards using various manufacturers' audio chipsets. Dolby True HD: Dolby True HD is an advanced lossless audio codec. Dolby TrueHD supports 24-bit, 96 khz audio channels at up to 18 Mbit/s over 14 channels (HD DVD and Blu-ray Disc standards currently limit the maximum number of audio channels to eight). It supports metadata, including dialog normalization and Dynamic Range Control. Dolby Surround: Dolby Surround was the earliest consumer version of Dolby's multichannel analog film sound decoding format Dolby Stereo. When a Dolby Stereo / Dolby Surround soundtrack is produced, four channels of audio information - left, center, right, and mono surround - are matrix-encoded onto two audio tracks. The stereo information is then carried on stereo sources such as videotapes, laserdiscsand television broadcasts from which the surround information can be decoded by a processor to recreate the original four-channel surround sound.

75 69 AAC: Advanced Audio Coding (AAC) is a standardized, lossy compression and encoding scheme for digital audio and is a part of the MPEG-4 Systems Standard. Designed to be the successor of the MP3 format, AAC generally achieves better sound quality than MP3 at similar bit rates. An AAC encoded file can include up to 48 full-bandwith audio channels (up to 96 khz) and 15 Low Frequency Enhancement channels (limited to 120 Hz) plus 15 data streams. AAC encoding methods are organized into Profiles (MPEG-2) or Object Types (MPEG-4). These different Object Types are not necessarily compatible with each other and may not be playable with various decoders. MPEG-1 Audio Layer II (Also known as MP2): MPEG-1 Audio Layer II is a lossy audio compression format defined by ISO/IEC and primarily used in European countries. MP2 is an audio codec, and is the dominant standard for audio broadcasting. It is similar to MP3, but MP3 has become the dominant standard for PC and Internet applications. MP2 can have sampling rates of 32, 44.1 and 48 khz and bitrates of 32, 48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256, 320 and 384 kbit/s. PCM: Pulse-code modulation (PCM) is a method used to digitally represent sampled analog signals. It is the standard form for digital audio in computers and various Blu-ray, Compact Disc and DVD formats, as well as other uses such as digital telephone systems. A PCM stream is a digital representation of an analog signal, in which the magnitude of the analogue signal is sampled regularly at uniform intervals, with each sample being quantized to the nearest value within a range of digital steps.

76 70 Digital Tech Tips BER (Bit Error Rate) is the ratio of errored bits to the total number of bits transmitted, received, or processed over a defined length of time. Example: 3 errored bits in a total of 1,000,000 transmitted bits will result in a BER of: 3/1,000,000 = = 3 x MER (Modulation Error Ratio) is the ratio, in decibels, of average symbol power to average error power: MER(dB) = 10 x log (average symbol power / average error power) MER is influenced by everything present in the signal s transmission path such as: Phase Noise; CNR (Carrier-to-Noise Ratio); CTB distortion (Composite Triple Beat); CSO distortion (Composite Second Order); Cross Modulation (X-mod); Micro-reflections (Ghosting); Amplitude tilt/ripple; Group Delay; Ingress. (8VSB) (QAM 64) (QAM 256) to To help maintain the relative signal level difference between Analog and Digital channels, after adjusting for a sloped output from the amplifier, do the following: When using QAM 64, set signal level of digital channels 8 to 10 db below the equivalent Analog channels. When using QAM 256, set signal level of digital channels 6 to 8 db below the equivalent Analog channels.

81 Digital Signal Analysis 75 Digital signals such as QPSK & QAM use many different factors to determine the quality and performance of the signal. The following section will describe some of the most common factors used in digital signal analysis. QAM Signal to Noise Ratio vs. BER The theoretical bit-error rate of the QAM signal as a function of the SNR is provided for reference. To obtain an estimated BER of the QAM signal, one can use the following diagram to get theoretical values for BER. In the case that the QAM 64 mode SNR is >32, it indicates BER. It should be noted that changing the S/N value by as little as 1 db alters approximately one decade. The diagram below depicts the theoretical BER vs. SNR.

82 76 Digital Signal Analysis QAM Signal to Noise Ratio The following table depicts the theoretical maximum values for various orders of QAM: Order of QAM SNR max db db db db db db QAM MER Modulation Error Ratio The modulation error is a calculated quantity indicating the mean or the maximum deviation of the I/Q values from ideal signal states and thus provides a measure of signal quality. The following diagram shows the vectors used for calculating the modulation error:

83 77 The modulation error is specified as rms and as peak value. To calculate the modulation error, all decisions fields are investigated on after the other: To obtain peak modulation error, the maximum magnitude of the difference vector (error vector) formed by the vector of the ideal and the actual signal status is determined for each decision field. From the maximum value of these results, the peak MER (modulation error ratio) is calculated using the following formula: To obtain the rms modulation error, the squares of the magnitude of all differential vectors formed by the ideal-status and actualstatus vectors are added up, and the number of symbols is counted. Then the rms modulation error is calculated as follows: The peak and rms modulation error can also be specified on a logarithmic scale. Conversion is done using the following formula:

84 78 Digital Signal Analysis For quantized I/Q values, the peak value is output in discrete form only since no averaging is performed in the calculation. The rms modulation error can be calculated within the limit values specified in the following table. The limit values are obtained for quantized I/Q values: Order MER RMS MER PK MER PK MER db of QAM min min min max % % % 46 db % % % 46 db % % % 43 db % % % 46 db % % % 43 db % % % 46 db The term Modulation Error Ratio and the prescribed method of calculation were declared an international standard by the DVB Measurement Group.

85 79 What is a QAM Signal Quadrature Amplitude Modulation (QAM) uses many different phases known as states: 16, 32, 64, and 256. Each state is defined by a specific amplitude and phase. This means the generation and detection of symbols is more complex than a simple phase or amplitude device. Each time the number of states per symbol is increased the total data and bandwidth increases. The modulation schemes shown occupy the same bandwidth (after filtering), but have varying efficiencies (in theory at least). QAM Constellation Diagrams Constellation diagrams are used to graphically represent the quality and distortion of a digital signal. In practice, there is always a combination of modulation errors that may be difficult to separate and identify, as such, it is recommended to evaluate the measured constellation diagrams using mathematical and statistically methods. The following section will provide application and interpretation information of constellation diagrams of digital modulated signals.

86 80 Digital Signal Analysis The constellation diagram examples shown are based on 64 QAM modulation and use the following basic settings: maximum possible DVB data transmission rate of 6.92 Msps or Mbit/s (64 QAM); Cosine roll-off filtering with roll-off factor r = 0.15 and PRBS (pseudo random binary sequence) data stream, no coding. Constellation Diagram for an Ideal 64 QAM Signal Amplitude Imbalance describes the different gains of the I and Q components of a signal. In a constellation diagram, amplitude imbalance shows by one signal component being expanded and the other one being compressed. This is due to the fact that the receiver AGC makes a constant average signal level. Phase Error is the difference between the phase angles of the I and Q components referred to 90. A phase error is caused by an error of the phase shifter of the I/Q modulator. The I and Q components are in this case not orthogonal to each other after demodulation.

87 81 Interferers are understood to be sinusoidal spurious signals occurring in the transmission frequency range and superimposed on the QAM signal at some point in the transmission path. After demodulation, the interferer is contained in the baseband form of low-frequency sinusoidal spurious signals. The frequency of these signals corresponds to the difference between the frequency of the original sinusoidal interference and the carrier frequency in the RF band. In the constellation diagram, an interferer shows in the form of a rotating pointer superimposed on each signal status. The example applies the condition that there is no other error present at the same time, The constellation diagram shows the path of the pointer as a circle around each ideal signal status. Constellation Diagram 64 QAM signal with Interferer (C/I = 25.0 db)

88 82 Digital Signal Analysis Carrier suppression or leakage is a special type of interference in which it s frequency equals the carrier frequency in the RF channel. Carrier leakage can be superimposed on the QAM signal in the I/Q modulator. In the constellation diagram, carrier leakage shows up as a shifting of the signal states corresponding to the DC components of the I and Q components. Additive Gaussian noise can disturb the digitally modulated signal during analog transmission, for instance in the analog channel. Additive superimposed noise normally has a constant power density and a Gaussian amplitude distribution throughout the bandwidth of a channel. If no other error is present at the same time, the points representing the ideal signal status are expanded to form circular clouds. Constellation Diagram 64 QAM signal with Additive Noise (SNR = 30.0 db) (Note: This diagram may also be obtained for other types of interference so that a distinction from noise-produced patterns cannot be made)

89 83 Phase Jitter or phase noise in the QAM signal is caused by transponders in the transmission path or by the I/Q modulator. It may be produced in carrier recovery, a possibility that is to be excluded here. In contrast to the phase error described above, phase jitter is a statistical quantity that affects the I and Q path equally. In the constellation diagram, phase jitter shows up by the signal states being shifted about their coordinate origin.

95 Analog Content Types 89 Component video Video is an analog video-only signal that is transmitted as three separate signals. Component-video cables do not carry audio and are often paired with audio cables. Component video is capable of carrying signals such as 480i, 720p, and 1080i and most high-definition TVs support the use of component video up to their native resolution. The three most commonly used component types are: YP b P r YP bp r is the converted version of RGB which is split into three components: Y carries luma (brightness) and sync information; Pb carries the difference between blue and luma; and Pr carries the difference between red and luma. The primary advantages of YPbPr over RGB and S-video is that it is able to transfer non-interlaced video and, and at the same time, provide high resolution video such as 1080i or better. RGB RGB (Red, Green, Blue) uses no compression and contains redundant data since most programs typically contain the same black & white image, therefore, it requires large bandwidth to carry the signal. It s becoming obsolete as home theaters move toward HDMI and computers toward DVI interfaces. S-Video S-Video (Separated Video) is an extension of the analog Composite standard. Compared to the two standards above, it provides the poorest quality of image. It s rarely used for today s applications because it cannot be used for high definition standards unless its standard is changed to accommodate for signal modulation of the carrier frequency.

96 90 Analog Content Types Composite Video is an analog video-only signal which is a composite of three source signals called Y, U, and V. Y represents the brightness of the picture and includes synchronizing pulses, so that by itself it could be displayed as a monochrome picture. U and V represent hue and saturation and carry the color information For residential and commercial applications, the composite video signal is typically connected using an RCA jack, normally yellow, which is often accompanied with red and white for right and left audio channels.

97 Analog Closed Captioning 91 Closed captioning rules and regulations are found in FCC 47 C.F.R (part 79). Closed captioning information is embedded in the program/ signal and is decoded and displayed by the television. For all types of NTSC programming, captions are "encoded" into Line 21 of the vertical blanking interval. Line 21 closed captioning has two styles: 1. Scrolling (or Roll-up), and 2. Block (or Pop-on). It allows for up to four caption services per program and provides the limited range of white characters with-in a boxed black background. The Line 21 data stream can consist of data from several data channels multiplexed together. Field 1 has four data channels: two Captions (CC1, CC2) and two Text (T1, T2). Field 2 has five additional data channels: two Captions (CC3, CC4), two Text (T3, T4), and Extended Data Services (XDS). XDS data structure is defined in CEA 608. As CC1 and CC2 share bandwidth, if there is a lot of data in CC1, there will be little room for CC2 data. Similarly CC3 and CC4 share the second field of line 21. The FCC recommends bilingual programming should have the second caption language in CC3.

124 118 System Calculations Composite Intermodulation Noise (CIN) It is assumed that CIN is dominated by 3rd order distortion (CIN3). This is the case in systems with analog television channels to 550 MHz and digital video above 550 MHz. 1. Composite Intermodulation Noise for One Amplifier at Operating Level. 2.

FCC Requirement C/N = 43 db N = Number of equal contributors NF = Noise Figure = Thermal Noise in 4 MHz Bandwidth (dbmv)

127 121 Determining Acceptable Peak-to-Valley Deviation To determine what degree of overall peak-to-valley deviation is acceptable for the Nth amplifier in a cascade, use this formula. Where x is equal to the acceptable P-V deviation and, N = number of amplifiers in cascade. For example, what is the maximum acceptable peak-tovalley deviation at the 32nd amplifier in a cascade? Thus, 4.2 db is the maximum acceptable peak-to-valley deviation (highest peak to lowest valley in the broadband signal) at the 32nd amplifier.

129 123 Amplifier Cascade Factor - Example The Amplifier Cascade Factor Chart (on previous page) is used to predict performance considering the contribution of various numbers of amplifiers. It assumes that all amplifiers are operated at the same level (input level for noise, output level for distortion). This is generally the case in a Unity Gain Based System. Example: What is the trunk CTB after 13 trunk amplifiers? Given: 1. Single trunk amplifier CTB specification is dbmv flat (from Manufacturers specs.) 2. Trunk output is 25 dbmv, channel 2 Trunk output is 32 dbmv, channel 60 (7 db linear tilt) Step 1 Re-rate performance of single amp based on actual operating level. Geometric tilt center = 28.5 dbmv Add.5 db correction factor = 29 dbmv average level = 3 db x 2 (for CTB) = 6 db 87 db + 6 db = 93 db 29 dbmv average level Step 2 Find cascade factor for CTB for 13 amps, on the chart = db Step 3 Subtract cascade factor from single amp operating performance 93 db = db CTB = db after 13 amps

130 124 System Calculations Note: Summing different ratios requires a grasp of the antilog concept. For brevity, the example shown is for CTB only, but the approach is identical for all system distortion and noise calculations. Determine End Of Line CTB Given The Following: 10 Trunk CTB = 65 dbc 1 Bridger CTB = 60 dbc 3 Line Extender CTB = 58 dbc Step 1. CTB s = 20 log ( ) Step 2. CTB s = 20 log ( ) CTB s 20 log (antilog antilog antilog -2.90) Note: To perform the operations in step 2, use the inverse log or antilog function on most calculators. Antilog (Inverse Log) is used to re-express the different exponent values to voltage so the amounts may be easily summed. Don t forget the minus sign Step 3. CTB s = 20 log (5.62 x x x 10 ) Step 4. CTB s = 20 log (5.62 x x x 10 ) -4 Step 5. CTB s = 20 log (28.12 x 10 ) CTB = 51 dbc The 20 Log and 10 Log function derate charts & example on pages 86, 87 and 88 may also be used to sum different ratios if a scientific calculator is not available.

The following example demonstrates how: Step 1 Sum Trunk and Bridger CTB 1.1 Find the db difference between the two ratios (65-60=5 db) 1.2 Look up the derate (db Subtraction) for 5.0 db difference in the chart (3.88 db) 1.3 Derate the poorer of the two CTB ratios by this amount (60-3.9=56.1 dbc) Step 2 Sum the Sum of Trunk and Bridger from Step 1 with the line extenders 2.1 Find the db difference between the two ratios ( =1.88) 2.2 Look up the derate (db Subtraction) for 1.88 db difference in the chart (5.12) (round 1.88 up to 1.9). 2.3 Derate the poorer of the two CTB ratios by this amount ( = 51.0 dbc) Combining Two CNR or SSO Performance Ratings (10 Log) Using db Subtraction Values 10 Trunk CNR = 56.5 db Example: Combine trunk and bridger 1 Bridger CNR = 65 db CNR to find the resultant CNR at the Bridger output (no line extenders). db difference = = 8.5 db db subtraction figure = 0.6 db Bridger output CNR = = 55.9 db So then, the resultant CNR measure is about 55.9 db. 127

134 128 Passive & Coaxial Cable Characteristics Cable and Equalizer Formulas 1. Cable Loss Ratio The ratio of cable attenuation at two frequencies is approximately equal to the square root of the ratio of the two frequencies. Example: To calculate the approximate cable loss at 55 MHz when the loss at 450 MHz is 20 db, 2. Tilt to Cable Loss To convert tilt (differential in signal level between end frequencies of the cable bandpass) to cable loss at the highest frequency: Example: To calculate the cable loss at the highest frequency when the measured tilt is 12 db between 55 and 450 MHz

135 Broadband RF Network Powering 129 When determining the power supply location in a cable system, it is important to know OHM s Law, cable loop resistance, amplifier current drain and the minimum operating voltage required for amplifier operation. The cable resistance is included in the manufacturers specification sheet. Resistance is usually stated as center conductor, shield, and loop. Loop resistance is the sum of the center conductor and shield resistance. The amplifier current drain and voltage requirements are also part of the manufacturers specifications. The ideal location of the power supply is such that the current supplied flows equally both, away from, and towards the headend. The total current supplied should be between 80-90% of the power supply s rated output. Current passing through the amplifiers is usually limited to about 6 Amps. Since power supplies are available with various current handling abilities, one with slightly higher capability than required should be selected. Determining power supply placement, refer to the figure on the next page. 1. First determine the loop resistance for each span of cable. Example: Loop resistance = 1.7 Ohms/1000 ft. x 800 = 1.36 Ohms. 2. Locate the last amplifier, determine the voltage drop across the span of cable. 3. Using the current draw of the amplifier, determine the voltage drop across the span of cable. Example: 0.375A x 1.36 Ohms = 0.51 volts. 4. Since the minimum operating voltage for the amplifier is 43 volts, the voltage level at the beginning of the 800 span would be 43.5 volts ( ). 5. At this point, the total current flow in the coax will increase due to the addition of another amplifier. Current flow in this span of cable will be 0.75A ( ).

136 130 Broadband RF Network Powering 6. Determine the voltage across the next span of cable x 1.36 Ohms = 1.02 Volts Therefore the voltage at the output of the bridger amp is 44.5 volts. The total current at the input to the bridger amp is 2.0 amps. This is the sum of both output legs of the bridger (1.5A) and the current draw of the bridger amp itself. 7. Continue working towards the headend until the current draw is 40-50% of the power supplies rated capability or the voltage level nears 60 volts. 8. At this time, a guesstimate of where to place a power block in the section between the power supply and headend must be made. Add the current draw for the line extender(s) off each trunk station to the trunk station current requirements. A few trial calculations will show how many amplifiers can be powered going in this direction.

162 156 Basic Cable Theory The Decibel The decibel (db) provides a means of representing large power ratios as manageable, small numbers, and allows the overall gains and losses in a module or a network to be calculated by addition and subtraction, rather than by multiplication and division. The original unit is the Bel (named after Alexander Graham Bell). The decibel is one-tenth of a Bel. The power ratio of two power measurements is calculated as follows: Ratio of power P1 to power P2, in db: The power ratio of two voltage measurements is calculated as follows: Power ratio of voltage V1 to voltage V2, in db: Voltage Confusion dbmv and dbµv expressions of power contain an upper case V. This does not mean they are expressions of voltage. They are expressions of power. When all the power scales (dbm, dbmv and dbµv) are laid next to each other, it is easy to see that each track on a db for db basis.

163 Power Conversions 157 dbmv A power measurement of x dbmv indicates that a particular signal is x db greater than ( above ) 1 millivolt in 75 ohms. A negative dbmv value indicates that the signal is x db less than ( below ) 1 millivolt in 75 ohms. To convert x millivolts to dbmv: dbµv Similarly, a measurement of x dbµv indicates that the signal is x db above one microvolt in 75 ohms. To convert x microvolts to dbµv: To convert dbmv to dbµv, add 60 to the dbmv reading: dbm A measurement of x dbm indicates that a particular signal is x db greater than ( above ) 1 milliwatt. A negative dbm value indicates that the signal is x db less than ( below ) 1 milliwatt. To convert x milliwatts to dbm:

164 158 Power Conversion A power level, in dbmv, can be converted directly to power in dbm, if the impedance, Z. is known: To convert x dbmv directly to dbm: The inverse operation is also possible if impedance is known: To convert dbm directly to dbmv: Impedance Mismatch It frequently happens that the input impedance of a measuring device (spectrum analyzer; field strength meter, etc.) does not match the impedance of the system under test. In such a case, a correction must be made to the reading displayed on the instrument. Where Zi is the impedance of the instrument, and Zs is the impedance of the system under test.

174 Ohm Attenuator Table & Equations The equations necessary to calculate the resistance values in ohms for T and Pi pad Attenuators are as follows: where: n = loss in db z = impedance value in Ohm To obtain resistance values at various impedances, simply multiply the resistances by the impedance value. Example: Given n = 2.0, calculate the resistance values for a 75 Ohm T-Attenuator:

175 Passive & Coaxial Cable Characteristics 169 Cable and Equalizer Formulas 1. Cable Loss Ratio The ratio of cable attenuation at two frequencies is approximately equal to the square root of the ratio of the two frequencies. Example: To calculate the approximate cable loss at 55 MHz when the loss at 450 MHz is 20 db, 2. Tilt to Cable Loss To convert tilt (differential in signal level between end frequencies of the cable bandpass) to cable loss at the highest frequency: Example: To calculate the cable loss at the highest frequency when the measured tilt is 12 db between 55 and 450 MHz

176 170 Cable and Equalizer Formulas 3. Equalizer Loss at any Frequency To calculate the equalizer loss at any frequency, the following formula may be used: Example: To calculate the loss of an equalizer for 20 db of cable at 450 MHz at a frequency f1 of 55 MHz,

177 Cable Loss Conversion Chart Use this chart to find a cable span s attenuation at a new frequency if you already know its attenuation at one frequency. If you know the cable loss at f 1 and want to find the corresponding loss at a higher frequency f 2 multiply the loss at f 1 by the conversion factor. The result is the cable loss at f 2. If you know the cable loss at f 2 and want to find the corresponding loss at a lower frequency f 1 divide the loss at f 2 by the conversion factor. The result is the cable loss at f 1. f 1 f 2 f 1 f 2 (MHz) (MHz) (MHz) (MHz) Example: If a cable span attenuates a 220 MHz signal by 10 db, by how much will it attenuate a 300 MHz signal? Loss at 300 MHz = Loss at 220 MHz x conversion factor = 10 db x = db 171

178 172 Cable Loss and Temperature This equation calculates the percentage of change in cable attenuation (loss) caused by a temperature change: % change in cable loss = 1.1% per 10 F This equation calculates the change in cable loss in a span of cable, expressed in db. change in cable loss (in db) = standard loss x % change in cable loss Example: If the standard loss is 22 db* when the temperature is 70 F and the temperature drops to -40 F, what is the change in attenuation for that cable span? 1. Determine the number of degrees of temperature change. T = T 2 - T 1 = (-40 F) - 70 F = (-110 F) 2. Find the percent change in cable loss. % change = 1% per 10 F x (-110 F) = (1%/10 F) x (-110 F) = - 11% 3. Find the db change in the span s loss. Change in cable loss (in db) = -11% x 22 db = db So, if the span s loss was 22 db at 70 F it becomes 22 db + (-2.42 db) = db at -40 F. Changes in cable loss accumulate over multiple cable spans and can cause performance degradation if not controlled by AGC/ASC units.

194 188 FCC Rules Cumulative Leakage Index Cumulative Leakage Index (CLI), also referred to as a figure of merit measurement, is a method for assessing the leakage integrity of a cable plant. The cable operator demonstrates compliance with a cumulative signal leakage index by showing either that: using either: where: r ø R E n and where: = Distance in meters (m) between the leakage source and the center of the cable system. = Fraction of the system cable length actually examined for leakage sources. The fraction is equal to the strand miles tested divided by total strand miles. = Slant height distance (m) from leakage source i to a point 3,000 meters above the center of the cable system. = Electric field strength in microvolts per meter (µv/m) measured 3 meters from leak i. = Number of leaks found with a field strength 50 µv/m.
