Audemat FM/HD Probe is an RF monitor for FM, RDS and HD1–HD3 with advanced QoS/QoE analysis, NRSC mask monitoring, spectrum tools, streaming, recording and alarms.
The Audemat FM/HD Probe RF Monitor QoS & QoE is a next-generation monitoring platform designed to supervise both FM and HD Radio services from a single 1U unit. It provides simultaneous monitoring of HD1, HD2 and HD3 alongside full FM and RDS analysis, helping broadcasters verify signal integrity, audio quality and metadata across their entire on-air chain.
The system continuously tracks carrier presence, RF level, audio levels and RDS or HD metadata, with precise tools to measure FM/HD alignment and audio delay between analog and digital paths. Advanced NRSC mask monitoring and real-time RF, MPX and audio spectrum analysis enable engineers to confirm regulatory compliance and rapidly detect any out-of-tolerance conditions. In addition, the unit can stream and record audio in real time for both FM and HD services, providing a clear audit trail for incident investigation and quality checks.
Audemat FM/HD Probe is an ideal off-air companion for modern HD-capable transmitters such as the
Nautel GV2 Series FM/HD HD-ready transmitters or the HD Radio optional Nautel NVLT and VS Series transmitters, providing continuous verification that FM and HD services, time alignment and metadata arriving at listeners match the performance of the transmission plant.
