Matrix Test Equipment Incorporated
The MATRIX Model HD-500 is a detector-amplifier designed to demodulate the low frequency amplitude modulations on any RF carrier over the range of 5 to 1500 MHz. These modulations are usually the undesirable result of the 50 or 60 Hz power source and are not necessarily sinusoidal. The unit is calibrated to the SCTE definition of hum modulation, which is the ratio of the peak-to-peak hum modulation to the peak of the carrier.
