The Inovonics 525N is a third-generation AM Modulation Monitor that can accept either a direct feed from the transmitter, or function as a precision Reference Receiver to give accurate off-air measurements reflecting ATU, phasor and antenna parameters. A proprietary phase-locked synchronous detector provides precise demodulation, rejects interference and recovers only the amplitude-modulated component of HD Radio ‘hybrid digital’ transmissions.
