Combined with a Network Monitoring System or not, the EdgeProbe RF provides a powerful network alert and diagnosis tool, allowing DTV network operators to monitor global trends and anticipate potential failures. EdgeProbe RF is able to monitor DVB-T and DVB-T2 signals at transmitter outputs through its RF input. It can continuously log all events and measurement values in an archive file, and can send SNMP traps if selected parameters’ values exceed defined thresholds. For troubleshooting, a low bandwidth Web GUI gives access to all monitored parameters, from RF to baseband. EdgeProbe RF provides signal monitoring at different levels: • RF transmission: measures key RF signal parameters (Level, MER, SNR, BER) and indicates the modulation parameters as well as the Channel Impulse Response (CIR). • MPEG-2 TS: checks the ETSI TR 101 290 (Priority 1, 2 and 3) conformance and provides Quality of Service indicators (Service Availability, Service Degradation).
