146 5.14 Line Decoding Line Decoding (1) NRZI (Non return to zero, inverted) Non return to zero, inverted (NRZI) is a method of mapping a binary signal to a physical signal for transmission over some transmission media. The two level NRZI signal has a transition at a clock boundary if the bit being transmitted is a logical one, and does not have a transition if the bit being transmitted is a logical zero. There are two modes: a. NRZI (Transition occurs for a one) A 1 is represented by a transition of the physical level, a 0 has no transition. b. NRZI (Transition occurs for a zero) A 0 is represented by a transition of the physical level, a 1 has no transition. (2) Manchester In telecommunication, Manchester code is a line code in which the encoding of each data bit has at least one transition and occupies the same time. It is, therefore, self-clocking, which means that a clock signal can be recovered from the encoded data. 146

147 There are three modes: a. Manchester (Thomas) A 0 is expressed by a low-to-high transition, a 1 by high-to-low transition. b. Manchester (IEEE802.3)A 1 is expressed by a low-to-high transition, a 0 by high-to-low transition. c. Differential Manchester A 1 bit is indicated by making the first half of the signal equal to the last half of the previous bit's signal i.e. no transition at the start of the bit-time. A '0' bit is indicated by making the first half of the signal opposite to the last half of the previous bit's signal i.e. a zero bit is indicated by a transition at the beginning of the bit-time. In the middle of the bit-time there is always a transition, whether from high to low, or low to high. A reversed scheme is possible, and no advantage is given by using either scheme. 147

148 (3) Biphase Mark The biphase mark code (also called FM1 code) is a type of encoding for binary data streams. When a binary data stream is sent without modification via a channel, there can be long series of logical ones or zeros without any transitions which makes clock recovery and synchronization difficult. When encoding, the symbol rate must be twice the bitrate of the original signal. Every bit of the original data is represented as two logical states which, together, form a bit Add a Line Decoding Click Add Bus Decode in the Label menu or right-click on the label field to show the dialog below. 148

152 (3) Biphase Mark The biphase mark code (also called FM1 code) is a type of encoding for binary data streams. When a binary data stream is sent without modification via a channel, there can be long series of logical ones or zeros without any transitions which makes clock recovery and synchronization difficult. When encoding, the symbol rate must be twice the bitrate of the original signal. Every bit of the original data is represented as two logical states which, together, form a bit. (4) AMI (Alternate Mark Inversion) There are four modes: a. AMI (Standard) AMI (Alternate Mark Inversion) is a synchronous clock encoding technique that uses bipolar pulses to represent logical 1 value. It is therefore a three level system. A logical 0s is represented by no symbol, and a logical 1 is represented by pulses of alternating polarity. b. AMI (B8ZS) :Bipolar-8-Zero Substitution 152

153 If 1 is +, is represented to is -, is represented to c. AMI (HDB3) :High Density Bipolar 3 The HDB3 code is a bipolar signaling technique (i.e. relies on the transmission of both positive and negative pulses). It is based on Alternate Mark Inversion (AMI), but extends this by inserting violation codes whenever there is a run of 4 or more 0's. This and similar (more complex) codes have replaced AMI in modern distribution networks. The encoding rules follow those for AMI, except that sequences of four consecutive 0 s are encoding using a special "violation" bit. This bit has the same polarity as the last 1-bit which was sent using the AMI encoding rule. The purpose of this is to prevent long runs of 0's in the data stream that may otherwise prevent a DPLL from tracking the center of each bit. Such a code is sometimes called a "run length limited" code, since it limits the runs of 0 s that would otherwise be produced by AMI. One refinement is necessary, to prevent a dc voltage being introduced by excessive runs of zeros. This refinement is to encode any pattern of more than four bits as B00V, where B is a balancing pulse. The value of B is assigned as + or -, so as to make alternate "V"s of opposite polarity. The receiver removes all Violation pulses, but in addition a violation preceded by two zeros and a pulse is treated as the "B00V" pattern and both the violation and balancing pulse are removed from the received bit stream. This restores the original bit stream. 153

154 d. MLT-3:Multilevel Transmission 3 A 0 has no transition, a 1 is represented by a transition (0, +, 0, -). (4) Pseudoternary A 1 is always zero, a 0 is represented by a transition (+, -). (5) CMI (Coded Mark Inversion) A zero is sent a low to high [01] transition, while a one is sent as either a one [1] or zero [0] depending on the previous state. If the previous state was high the one is sent as a zero [0], if it was low the one is sent as a one [1]. 154

274 7.1 How to use Digital Data Logger? Use time This feature is only available in TravelLogic Series Start the Digital Data Logger It is able to record the acquired data for a long time as a log file xxx.log and independent of the LA Viewer. To use the record model only to record the transitional data (rising or falling edge), therefore, the overall amount of data transmitted will decrease because the data don t change. You can find and click the Data Logger icon ( ) in the programs (Start\All Programs\Acute Logic Analyzer\Digital Data Logger) of your PC to show the dialog box below. Parameters (1) File Enter the file name as xxx.log. (2) Sampling Rate In "Hz", can be an integer or decimal number. The maximum value is 50MHz. (3) Channels The number of channels recorded. 274

275 (4) Auto stop after XX sec. Stop Data Logger after the time (in seconds). (5) Time sec. The time (in seconds) being running Data Logger. Note: The logged file may lose some data if the sampling rate is high and will mark in the file. If this occurs, the program will place in the data leakage, marked Lose data. (6) Filter Setting You may filter the logged data in the Filter setting dialog below. Filter conditions are 0:Low 1:High X:Disable :Low to High :High to Low :Change. The data of each channel can be saved in any one condition. 275

276 (7) Threshold Setting You may also set the threshold for the data logger Data Format An example of the acquired data, consisting of Information (sampling rate and format in green box), Time (in decimal number when the edge changes in red box) and Data (in hexadecimal number in blue box), is shown below. The first data recording time is not necessarily 0, because the internal counter will start from power after the count. Therefore, it is normal. If it is found much record time interval, because data did not change, so do not record data, this is normal. The sampling rate is 1000Hz, in the red box denotes the edge changes at 26/1000th second and 00003FFFF in the blue box denotes the data value for 36 channels at 26/1000th second. Bit 0 of data for the channel
