DVB-C QAM/VSB Digital Cable

VB262

The VB262 Dual QAM/8VSB input option offers monitoring of cable TV signals as found in ITU-T J.83 Annex A/B/C QAM networks and DTT signals found in 8VSB networks. A chassis can be equipped with a VB120 or VB220 probe controller that has one or two VB262 RF input cards under its control.


A complete configuration with a fully licenced VB120 provides real-time monitoring and alarming for four QAM or VSB RF inputs, 50 IP MPTS/SPTS multicasts, upgradeable in steps of 10 from an initial 10 streams, and an ASI TS input and output. ETSI TR 101 290 analysis is performed in parallel for the QAM/8VSB inputs, the ASI input and the IP input. If the VB220 is used as master card, the IP monitoring capacity is increased to an impressive 260 MPTS/SPTS multicasts in addition to the RF inputs.


The combined unit is ideal for hybrid networks where IP is used as a carrier from head-end to the regional edge multiplexer/modulator/transmitter. The built-in round-robin functionality allows sequential analysis of multiple QAM or VSB multiplexes, making it possible to monitor the total broadcast contents of a cable transmission system using a single VB262. Each RF input port can be programmed to scan through 50 individual frequencies in a round-robin fashion.
