QBU-nano is a compact Pockels cell drivers producing high voltage quasi-rectangular unipolar pulses with high repetition rates, fast rise and fall time and adjustable pulse amplitude and pulse width. Wide temperature range of operation is another important feature.
The module requires +12 V DC power supply and a pulse generator to set an operating frequency and the pulse duration. An output voltage level (up to 5.8 kV) can be programmed in 70-100% level from VMAX range by user either manually (through onboard configuration trimpot) or automatically (applying a DC voltage between respective pins).
The output pulse duration is determined by time between two triggers, X3 and X4.
QBU-nano is based on avalanche transistors and offers fast transition time for both pulse edges.
