The 525N is a third generation AM modulation monitor from Inovonics. It can accept a direct feed from the transmitter or function as a precision reference receiver to provide accurate off-air measurements reflecting ATU, phasor and antenna parameters. A patented synchronous phase-locked detector provides accurate demodulation, rejects interference and recovers only the amplitude modulated component of HD Radio™ “hybrid digital” transmissions.
The 525N also supports power-saving MDCL operation. While the 525N maintains full wideband response for metering, it has user-selectable audio-monitor cutoff features to mitigate noise or to simulate the response of consumer radios.
IP connectivity with full SNMP support gives the user full access to the unit from any computer, tablet or mobile device. Configuration, metering, alarms and audio monitoring are available from the remote control point. The 525N is supplied with a wide aperture, weatherproof, passive AM loop antenna.
