VB260 QAM/RF INPUT MODULE

VB-260 Data Sheet The VB260 input option offers monitoring of QAM signals as found in QAM cable networks. The chassis can be equipped with a single VB120 or VB220 IP-PROBE master card and up to two VB260 QAM input cards under its control.

The complete configuration with the VB120 provides real-time monitoring and alarming for two QAM RF inputs, 10 IP MPTS/SPTS multicasts and one ASI TS input. ETSI TR 101 290 analysis is performed in parallel for QAM inputs, the ASI input and the IP input. If the VB220 is used as master card the IP monitoring capacity is increased to impressive 180 MPTS/SPTS multicasts. The combined unit is ideal for hybrid networks where IP is used as a carrier from head-end to the regional edge-multiplexer/modulator. The built-in round-robin functionality allows sequential analysis of multiple QAM multiplexes, making it possible to monitor the total broadcast contents of a cable transmission system using a single VB260.

The VB260 QAM/RF input option card is an ideal solution for complete monitoring in DVB-C or hybrid DVB-C/IP networks. One VB260 module is capable of demodulating a DVB-C multiplex for ETSI TR 101 290 fault detection and alarm generation in the full DVB-C frequency band (51 – 858 MHz). By running in sweep mode the VB260 module is further capable of measuring analogue signal levels, in effect offering the operator a basic frequency analyser function at the deployment location.
