Product Description

The AVRH series of pulse generators consists of three basic models providing output amplitudes in the range of 1000 to 3000 Volts into high impedance loads.
Model AVRH-3-B provides up to 3000 Volts out (to R ≥ 10 kΩ) with rise and fall times of 100 ns and pulse widths variable from 200 ns to 2.5 us. The pulse repetition frequency (PRF) is variable from 0 to 1.0 kHz, with a 0.25% duty cycle limit.
Model AVRH-2-B is similar but provides a maximum output of 2000 Volts (to R ≥ 10 kΩ) with a rise time of 80 ns. The pulse width is variable from 200 ns to 2.5 us, and the pulse repetition frequency is variable from 1 Hz to 1 kHz.
The MOSFET output stage for all models will safely withstand any combination of front-panel control settings, output open or short circuits, and high-duty cycles.
Aside from the internal clock, the units can also be triggered by a single-pulse pushbutton or an external TTL level trigger input. When triggered externally the output pulse width can be set to track the input trigger pulse width (PWOUT = PWIN). A delay control and a sync output are provided for scope triggering. A gate input is also provided.
Either (or both) output polarity can be provided
All models include a complete computer control interface. This provides GPIB and RS-232 computer-control, as well as front-panel keypad and adjust knob control of the output pulse parameters. A large backlit LCD displays the output amplitude, polarity, frequency, pulse width, and delay.
The output connector on standard units is an SHV jack. MHV or HN output connectors are optionally available.
All models are available with a DC-voltage-controlled output amplitude option (0 to +10 V).
