PVX-4000-2kV-EX 2kV Bipolar Pulse Generator

Please contact us for availability before placing orders.

+/- 2,000 V Bipolar High Voltage Pulser

Configured for user-supplied external HV power supplies.

The PVX-4000-2kV is an air cooled, high voltage pulse generator. Optimized for driving high impedance capacitive loads up to ±2000 V, the PVX-4000-2kV is well-suited for driving extraction grids and deflection plates for electrostatic modulation of particle beams in time-of-flight mass spectrometers and accelerators.

The PVX-4000-2kV-EX requires external high-voltage power supply sources from 0 V to ±2000 V. For example, a +1000 V supply can be connected to the positive voltage input and a -1000 V supply to the negative voltage input for a total of 2000 V. The differential voltage (difference between the positive and negative supply voltages) must not exceed 2000 V.

Using the internal trigger, the system is capable of duty cycles from 2% to 98% and repetition rates from 40 Hz to 30,000 Hz. With an external trigger, the system is capable of repetition rates from single shot to 600 kHz and pulse widths of 500 ns to 100% duty cycle.

Programming is accomplished through front panel controls as well as RS-232 and USB computer interfaces.

Computer Interfaces

For automated applications, complete control of the instrument is provided through RS-232 and USB computer interfaces. Up to five system configurations may be stored in internal nonvolatile memory, providing instant recall of frequently-used configurations.

Control Signals

Conveniently-located front panel BNC connectors allow the PVX-4000-2kV to be externally triggered.

The system has a Sync output for interconnection to other equipment. The pulse from the Sync output is synchronized to the leading edge of the output voltage pulse.

The output voltage waveform can easily be monitored through the Voltage Monitor BNC connection using an oscilloscope set to 1 MΩ termination.
