The PVX-4130 pulse generator produces fast, high volt-

age wave forms to 6,000V. Optimized for high impedance

capacitive loads, the PVX-4130 is well suited for driving

extraction grids and deflection plates for electrostatic

modulation of particle beams in time-of-flight mass spec-

trometers 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 in-

tensifiers. The exceptional pulse fidelity of the PVX-4130

will optimize the performance of any system in which it is

used.

The PVX-4130 generates an output voltage pulse of 6,000

volts with rise and fall times less than 60ns, with very flat

voltage pulses to DC into a capacitive load. It can gener-

ate singled-ended output pulses from ground to +6000V or

from ground to –6000V, and can also generate pulses

originating from a DC voltage offset from ground by using

both VLow and VHigh power supply inputs. This offset can

be from –6000V to +6000V, with a maximum power supply

voltage differential of

≤6000V.

The PVX-4130 requires 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.

is connected to the output. Therefore the PVX-4130 can be

used to generate a negative-going pulse by logically

inverting the input gate, so that the input gate is high until

input supply is connected to the output, thereby generating

a negative-going pulse.

The PVX-4130 features front panel indicator LEDs to moni-

tor the status of the pulse generator. Front panel voltage

and current monitors provide a straightforward means to

view the output voltage and current waveforms in real-time,

eliminating the need for an external high voltage oscillo-

scope probe.

The pulse generator is a direct-coupled, air-cooled solid-

state half-bridge (totem pole) design, offering equally fast

pulse rise and fall times, low power dissipation, and virtually

no over-shoot, under-shoot or ringing. It has over-current

detection and shut-down circuitry to protect the pulse gen-

erator from potential damage due to arcs and shorts in the

load or interconnect cable. All control and protection logic

circuitry, support power, energy storage and output network

are incorporated into the PVX-4130. It can be connected

directly to the load, and does not require series or shunt

resistors, impedance-matching networks between the

pulser and the load, or additional energy storage (capacitor

banks). All of this is taken care of within the PVX-4130.
