is connected to the output. Therefore the PVX-4140 can be
used to generate a negative-going pulse by logically
inverting the input gate, so that the input gate is high until
the unit is pulsed. When the input gate goes low, the V
LOW
input supply is connected to the output, thereby generating
a negative-going pulse.
The PVX-4140 features front panel indicator LEDs to moni-
tor the status of the pulse generator. Front panel instru-
ment-quality voltage and current monitors provide a
straightforward means to view the output voltage and cur-
rent waveforms in real-time, eliminating the need for an ex-
ternal high voltage oscilloscope 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-4140. 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-4140.
