The AV-112 family is designed for lower impedance loads (and thus higher average powers).The AV-112AH-PS is a high-power, variable-gain, high-voltage linear amplifier that accepts inputs of 0 to +/- 2 Volts, and amplifies the signal up to as much as +/- 200V, for operation into load impedances of 1.2 kilohms or higher. The amplifier bandwidth is 300 kHz. This instrument is ideal for amplifying the outputs of low-voltage arbitrary waveform generators.
