Frequently Asked Questions

The QBD-nano is a series of extremely compact Pockels cell drivers that produce high voltage bipolar pulses with fast rise times, fixed pulse durations, and slow voltage decay. It features adjustable pulse amplitude and a wide temperature range of operation.

The QBD-nano requires an input voltage of 5-12 V DC.

The pulse amplitude can be adjusted using the HV ADJUST trimpot within a range of 80-100% of UMAX. Additionally, applying a control voltage between PINS 1 and 2 on the INPUT/INTERFACE can further adjust the pulse amplitude.

The QBD-nano can achieve a maximum repetition rate of 1-10 kHz, depending on load, pulse amplitude, ambient temperature, and cooling conditions.

The QBD-nano operates within a temperature range of -40 to +65 degrees Celsius.

The QBD-nano produces high voltages that can be dangerous. It is important to read the user manual before operation and to measure the output with a symmetrical (differential) high voltage probe to avoid equipment failure.

The triggering signal applied to the QBD-nano should have an amplitude of 5 V (acceptable range is 3 V-8 V), an input impedance of 50 Ohms, a rising edge of less than 20 ns, and a duration greater than 20 ns.
