PVX-4450 Bi-polar Pulse Generator

The PVX-4450 is a bi-polar pulse generator designed for pulsing high impedance, capacitive loads at voltages up to ±1,750V returning to ground between pulses. A microprocessor-controlled TTL pulse generator is incorporated into the system, along with high voltage DC power supplies. This provides a stand-alone test system that can be programmed to perform your device testing using either the front panel LCD control panel, GPIB, or an RS-232 computer interface

The internal microprocessor-controlled pulse generator will allow the output pulses to be programmed synchronously (so that the pulse widths and delay between pulses are the same for both positive and negative pulses), or asynchronously (so that the positive pulses may be a different width than the negative pulses, and the delays between the positive-to-negative transitions and the negative-to-positive transitions can be different periods). Therefore the voltage of the positive phase can be different than the voltage of the negative phase. For example, the positive phase can be set to 1000V, and the negative phase to 600V, approximating a 60% decay. Furthermore, by setting either the positive or negative output to zero, the unit can be operated as a monophasic pulse generator, providing an output pulse up to +1,750 or –1,750V.
