DEI PVX-4000-2kV pulse generator from the United StatesProduct Introduction
Precision pulse control
PVX-4000-2kV is an air-cooled high-voltage pulse generator optimized for high impedance capacitive loads, which is highly suitable for providing driving voltage for the extraction grid and deflection plate of particle beam electrostatic modulation in time-of-flight mass spectrometers and accelerators.
system operation
The output voltage can be adjusted within the range of 0 V to ± 2000 V. The internal trigger source supports a duty cycle of 2% to 98% and a repetition rate of 40 Hz to 30000 Hz.
The device is equipped with a built-in trigger source and a built-in positive and negative high-voltage DC power supply, which can be used as an independent testing system. Programming operations can be completed through the front panel, RS-232, and USB computer interfaces.
When using an internal trigger source, the duty cycle will remain unchanged after adjusting the frequency, and the device will display a new pulse width. Suggest adjusting the frequency first, and then adjusting the pulse width.
When using an external trigger source, it supports pulse widths ranging from 500 ns to 100% duty cycle, as well as repetition rates from a single pulse to 100 kHz.
computer interface
For automation application scenarios, comprehensive control of instruments can be achieved through RS-232 and USB computer interfaces. The internal non-volatile memory of the device can store up to 5 system configurations and quickly retrieve commonly used configuration parameters.
control signal
The front panel is equipped with a convenient BNC connector, which can achieve external triggering of PVX-4000-2kV, with a gate input impedance of 50 Ω.
The system is equipped with a synchronous output interface that can be interconnected with other devices. The synchronous output pulse is synchronized with the rising edge of the output voltage pulse, and the synchronous output impedance is 50 Ω.
After setting the oscilloscope to 1 M Ω terminal matching, the system can be easily monitored through the voltage monitoring BNC interface.

Product Features
Excellent output performance, voltage regulation range of 0~± 2000V, voltage overshoot<2%, ultra fast rise/fall time in both high and low voltage ranges, * high ≤ 50ns, high pulse accuracy.
Flexible triggering mode, supporting internal/external dual triggering, with internal triggering ranging from 40Hz to 30kHz and external triggering ranging from single pulse to 100kHz. The pulse width is adjustable from 500ns to 100% duty cycle, suitable for multiple working conditions.
There are multiple control modes, which can be operated through the front panel, RS-232, and USB computer interfaces. The built-in non-volatile memory can store 5 configurations, and both automated applications and fast parameter tuning can be achieved.
Supporting functions, equipped with an external trigger with 50 Ω impedance, synchronous output interface, and a 1M Ω matched voltage monitoring interface, supporting multi device interconnection and real-time status monitoring, with strong system integration.
High adaptability in design, optimized for high impedance capacitive loads, air-cooled design, compact size (15 × 49 × 52cm), light weight (8kg), wide voltage supply (100-120/220-240VAC), good environmental adaptability.
The parameter adjustment is precise, and the frequency and pulse width are graded according to intervals to achieve high-precision resolution. When the internal trigger adjusts the frequency, the duty cycle can be kept unchanged, making the operation convenient and the parameter stability high.
Application scenarios
The PVX-4000-2kV air-cooled high-voltage pulse generator is optimized for high impedance capacitive loads and is suitable for use in equipment such as time-of-flight mass spectrometers and particle accelerators. It provides high-precision driving voltage for the extraction grid and deflection plate of particle beam electrostatic modulation; At the same time, with flexible triggering modes, precise pulse control, and interconnected monitoring functions, it can also be used as an independent testing system and applied to various laboratory research and industrial testing scenarios that require high-voltage pulse driving and high-precision pulse modulation.
