HCHV-3500 pulse generator

Product Introduction

HCHV-3500 pulse generatorCapable of generating fast high-voltage waveforms using an external voltage source of up to 3500V. This device is optimized for high impedance capacitive loads and is suitable for driving extraction gates and deflection plates to achieve electrostatic modulation of particle beams in time-of-flight mass spectrometers and accelerators. Its sturdy and multifunctional design also makes it suitable for use in pulse or gated power transistor gates, Pockels boxes and Q-switches, acoustic transducers, microchannel plates, photomultiplier tubes, and image intensifiers. The excellent pulse fidelity of HCHV-3500 will optimize the performance of any system using the device.

The HCHV-3500 generates output pulses of up to 3500V with rise and fall times of 25ns or less, capable of producing flat voltage pulses to DC under capacitive loads. Using an externally provided high-voltage power supply, the HCHV-3500 can generate single ended output pulses from ground to+3500V or from ground to -3500V, and can also generate DC voltage pulses offset from ground by using V-low and V-high power inputs. The offset range can be from -3500V to+3500V, with a maximum power supply voltage difference of ≤ 3500V.

HCHV-3500 requires user provided TTL gate signal, high-voltage DC power supply, and optional DC offset power supply input. The output pulse width and frequency are controlled by gate signals. The output pulse voltage is controlled by the amplitude of the input DC power supply.

When the device is enabled and the input gate is high, thenConnect the high-voltage power supply to the output. When the input gate is at a low level, the V low power supply is connected to the output. Therefore, HCHV-3500 can generate negative pulses by inverting the input gate through logic, keeping the input gate high before the device pulse. When the input gate becomes low, the V-low input power supply is connected to the output, generating a negative pulse.

The HCHV-3500 has a front panel indicator LED for monitoring the status of the pulse generator. The instrument level voltage and current monitor on the front panel provides a direct way to view the output voltage and current waveforms in real-time, without the need for an external high-voltage oscilloscope probe.
