The RCS 100 DAB from Gsertel is a 1RU rack-mount monitoring probe for continuous 24/7 quality surveillance of DAB/DAB+ digital radio broadcast networks. It performs simultaneous RF and transport-layer analysis — measuring SNR, MER (FIC and MSC), BER, RF power (-100 to +20 dBm), frequency offset (<10 Hz accuracy), SFN drift, and echo patterns — with integrated mask-based spectrum analysis from 5 MHz to 1 GHz.

How does the RCS 100 DAB alarm system work?

Alarms are fully configurable with user-defined thresholds across RF, ASI, IP, ETR290, service, PID blacklist, and PID bitrate categories. Each alarm has a configurable severity level (Info, Warning, Error) with color coding and a stabilization margin using configurable ON/OFF cycles (1–120 polling cycles) plus hysteresis thresholds — preventing nuisance alarms from transient RF conditions. Alarm actions include SNMP v2 traps, triggered transport stream recording, and visual indicators. Historical alarm logs include temporal evolution graphs and measurement correlation for root-cause analysis. System-level alarms cover temperature, power supply status (dual PSU models), and alarm deletion events.

How is the RCS 100 DAB accessed and managed?

All monitoring, configuration, and alarm management is performed through a built-in HTML5 web interface — no additional software required. SNMP v2 provides integration with network management systems for alarm forwarding and status polling. A front-panel graphic LCD (256×64) and local keyboard enable on-site access when network connectivity is unavailable. The unit processes all inputs simultaneously at up to 300 Mbps aggregate throughput and supports ETI-LI recording, audio silence detection, loudness metering per EBU Tech Doc 3341, and electronic program guide decoding. A redundant Gigabit Ethernet port provides failover network connectivity for mission-critical headend and transmitter site deployments.
