Magnetic Immunity Amplifier for Susceptibility Testing
AR RF/Microwave Instrumentation has unveiled a new magnetic immunity amplifier for susceptibility testing. Model 350AH1 (350 watts, 10 Hz – 1 MHz) automatically accepts voltages from 90 to 260 VAC in the 47 – 63 Hz frequency range. The new amplifier, which has very low output impedance, will be used primarily for susceptibility testing for magnetic and audio frequency tests in MIL-STD-461D/E, DO160D/E, and a variety of automotive test standards. It can also be used as an AC voltage source, for watt-meter calibration, and as a driver for higher-power amplifiers.
