Radio Engineering Associates is pleased to offer our AMM-SD1 (Software Display) series of AM Modulation Monitors. These devices represent a breakthrough in accurate, easy to use and highly cost effective instrumentation for measuring and monitoring Amplitude Modulation transmitters and signals.
How it works The AMM-SD1 Modulation Monitor uses with a USB connected, microprocessor based hardware interface and RF demodulator. The RF demodulator is generally connected to the transmitter (or transmission line). The microprocessor interface connects to the display computer using a USB cable.
