 20kHz Q switch driver

20kHz Q switch driver
This compact pulser is designed as a "Q" Switch driver, delivering around 950 volts into up to a 100pf load at 20kHz. The pulse width can be adjusted from around 12ns to 50ns. Rise time is load dependent but typically in the range 5 to 12ns. Runs from a 9 volt supply.

Precision delay generator

Precision Delay Generator
This is a delay generator using passive delay lines under computer control for very accurate delay of trigger signals. Each unit is carefully calibrated to remove manufacturing tolerances. It offers an insertion delay of 6.5ns and a maximum settable delay of 20ns in 25ps steps. The jitter is insignificant as the device is passive and the timing drift is only that caused by thermal expansion of the delay lines.
