(large scale)
The Model C12k-20 was designed to operate into high impedance/capacitive loads. This is a two switch pulser, one to turn on the high voltage and the second to turn off the high voltage, that is discharge the load and stray capacitances producing fast fall times. Capacitive loads up to 500 pF and resistive loads down to 5 meg ohm may be used.
