The AV-112 family is designed for lower impedance loads (and thus higher average powers). The AV-112B-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 +/- 135V, for operation into load impedances of 500 Ohms or higher. The amplifier bandwidth is 50 kHz. This instrument is ideal for amplifying the outputs of low-voltage arbitrary waveform generators.
