The PVM-4140 is a compact, OEM-style pulse generator module producing fast, high voltage wave forms to 3,000V. Optimized for high impedance capacitive loads, the PVM-4140 is well suited for driving extraction grids and deflection plates for electrostatic modulation of particle beams in time-of-flight mass spectrometers and accelerators. Its robust and versatile design also makes it well suited for pulsing or gating power tube grids, Pockels cells and Q Switches, acoustic transducers, microchannel plates, photomultiplier tubes and image intensifiers. The exceptional pulse fidelity of the PVM-4140 will optimize the performance of any system in which it is used. The PVM-4140 generates an output voltage pulse of 3,000 volts with rise and fall times less than 25ns, with very flat voltage pulses to DC into a capacitive load. It can generate singled-ended output pulses from ground to +3000V or from ground to 3000V, and can also generate pulses originating from a DC voltage offset from ground by using both VLow and VHigh power supply inputs. The PVM-4140 requires user-supplied +24VDC to +28VDC support power, a TTL gate signal, a high voltage DC power supply and optional DC offset supply inputs. The output pulse width and frequency are controlled by the gate signal. The pulse output voltage is controlled by the amplitude of the input DC power supplies.
