PVX-4000-2kV-EX Pulsed Voltage Source Datasheet

Precision Pulse Control

The PVX-4000-2kV-EX is an air-cooled, high voltage pulse

generator. Optimized for high impedance capacitive loads,

the PVX-4000-2kV-EX is well-suited for driving extraction

grids and deflection plates for electrostatic modulation of

particle beams in time-of-flight mass spectrometers and

accelerators.

+1000 V & -1000 V, 4 kHz, 100.0 µs, 344 pF Load

System Operation

The PVX-4000-2kV-EX system requires external high

voltage power supplies. Using external HVPSs, the output

voltage can be set from 0 V to ±2000 V. Duty cycles from

2% to 98% and repetition rates from 40 Hz to 30,000 Hz

are supported by the internal trigger source.

If using the internal trigger source, when changing the

frequency, the duty cycle is maintained and the new pulse

width is displayed. It is recommended that the frequency

be changed before the pulse width is changed.

Pulse widths from 500 ns to 100% duty cycle and repetition

rates from single-shot to 600 kHz are supported when an

external trigger source is used.

Computer Interfaces

+750 V & -750 V, 4 kHz, 100.0 µs, 344 pF Load

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 non-volatile memory, providing instant recall of

frequently-used configurations.

Control Signals

Conveniently-located front panel BNC connectors allow

the PVX-4000-2kV-EX to be externally triggered. The

impedance of the gate input is 50 Ω.

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 impedance of the sync output is 50 Ω.

The system can easily be monitored through the Voltage

Monitor BNC connection using an oscilloscope set to 1 MΩ

termination.

1. The PVX-4000-2kV-EX voltage source meets or exceeds

these specifications. The system was tested driving a

344 pF load at 2000 V output.

2. The factory supplied output cable has 1.57 pF / 1.0 cm of

cable. This needs to be calculated in the load value.

3. V_MONis designed to be used with RG 58/U 2ft long coax

cable connected between the V_MONBNC output and an

oscilloscope terminated in to a 1 M ohm input
