The Belar AMM-2C Modulation Monitor is a precision, all solid-state AM demodulator designed to measure the modulation characteristics of AM broadcast transmitters over a frequency range of 260 kHz to 50 MHz. The AMM-2C utilizes a unique carrier-referencing system for the peak flasher indications. Peak flasher accuracy, as well as modulation alarm sensitivity, is independent of carrier level over more than a ±30% range. A built-in calibrator checks the accuracy of modulation readings. Isolated outputs are provided for the built-in modulation and carrier level alarms. Remote outputs are provided for all modulation indications as well as the carrier level.
