Headend Station KAB 5000

Transcription

1 General Features is a complete range of programmable, signal processing modules for terrestrial, satellite and cable TV headends. All modules have identical format and are simply to place on a wall-fixing baseplate or in a 6RU rack-frame. RF and DC connections are carried out on the front panel using plug bridges supplied. RF input loop LNB powering BUS socket Programming port LED indicators Mounting in a 19 rack frame Mounting on a wall-fixing base plate 12V power cascade RF output loop Agility and Adjacent Channels KAB modules feature frequency agility handled by a high-performance PLL heterodyne double conversion. The broadband noise floor generated is exceptionally low, so multiple modules can be installed in the headend with very little deterioration of the CNR. The use of SAW filters provides, on the other hand, a true vestigial sideband response that enables frequency planning using adjacent channels. This characteristics mean the installations are highly flexible and the maintenance problems are simplified. Programming and Firmwareupdate The KAB modules are programmed and adjusted either with the PRG-5000 programming unit or with a PC with PRG-300 software installed. Programming process offers information about input BER and general operating status of the connected module. The parameter values are controlled in each module by a built-in, powerful microprocessor and remain unalterable unless they are modified with the PRG or PC. When using a PC, programming and setting can also be done remotely via modem. Firmwares of the modules and programming unit can be updated. 4.10

2 Functional Description of the Digital Satellite Receiving Modules QPSK tap line +12 V DC power cascade test TV multichannel output to the distribution network ~ LNB powering programming port DB-9 socket local bus 4-pin socket coupling line ~ test extension input amplifier KAV-47 An receiving module carries out the complete channel processing from the input to the output: tunes a QPSK Sat-IF digital channel in the band, selects a TV station from the multiplex received, and directs it to a conventional TV channel which is selectable throughout the band. Programming of each module involves the following selections and settings: Central Input Frequency (1 increments). Input Data Rate (0.001 MSym/s increments). TV Station and Audio Service. (or a Radio Station. Image will be black). Parameters of the output TV channel (video carrier frequency, TV system, colour system,video modulation depth, audio modulation index, carrier level ratio, output level). Image Format. Possible conversions are 16:9 to 4:3 Pan&Scan and 16:9 to 4:3 Letter-Box. Models featuring VSB output are utilizable for adjacent channel operation. If this operation is not required, existing model featuring DSB output may be used without problems. The first ones present, on the other hand, a very low broadband noise floor ( c) that permit to use multiple modules in the headend with very little deterioration of the CNR. The receiving modules feature two directionally coupled input and output ports. Sat-IF signal can therefore be directly fed into the input port of the first module, which in turn passes it through the coupler to the next and so forth. On the output side, the same procedure is repeated which forms the channel coupling. The sum of the combined channels is turn connected in the same way to the drive amplifier - the KAV-47 module or an external wideband amplifier - which then feeds the distribution network. For power connection, each module has two DC s that allow to build a +12 cascade. A third is available to connect the power for the attached LNB. Programming connection using the PRG-5000 is individual - module by module. When using a PC, programming may be local or remote. 4.11
