Inovonics 531N FM Modulation Monitor

Incorporating all the necessary features for station setup, regulatory compliance, and remote monitoring, Inovonics’ 531N is the ultimate choice for essential FM signal monitoring. Dependable, direct input and off-air reception lets you keep a sharp eye on your total RF signal performance whether you’re right at the transmitter site or half way around the world.

The high-resolution LED bargraph displays are easy to read, and a “floating dot” program peak marker eliminates any ambiguity in the total-mod measurement. Off-air readings are qualified by Inovonics’ exclusive multipath indicator, which also aids in antenna alignment during initial station build-outs. In addition, readouts of signal strength and synchronous AM noise qualify the incoming signal and validate measurements.

Synchronous AM Noise Monitoring – an exclusive with Inovonics.

Rear-panel alarms constantly check for Audio Loss, RF Loss, Multipath and Overmodulation, while advanced notifications alert personnel with e-mail or SMS messaging when any or all of the alarms occur.

Features:
– Complete set of metering and measurement tools to ensure FM broadcast regulatory compliance worldwide.
