The AV-151 series is a family of high-voltage (or, for the AV-151F, high-current) function generators and variable-gain amplifiers. All models include both an internal oscillator that can generate sine, triangle, and square waves, and a variable-gain amplifier mode, which permits generation of more complex high-voltage
waveforms. The AV-151J family operates at slightly lower amplitudes (to +/-400V), but operates at higher frequencies (to 50 kHz), and can drive lower-impedance loads (down to 10 kilohms). Models with the -B suffix also include a pulse mode of operation. The pulse mode allows the generation of a rectangular pulse waveform that swings from zero Volts to a positive voltage. The pulse width is adjustable up to 0.5 seconds. The maximum pulse duty cycle is 80%.
