QBX-08 is a dedicated Pockels cell EO driver designed for continuous pulsed applications, where output voltage value should be constantly adjustable. It is essentially a single channel signal amplifier, which could serve as an electro-optical modulator, being connected to a Pockels cell. But the application field is not limited by this.

The module requires +24 V DC power supply and waveform generator to set an operating voltage and signal form. The driver is based on a voltage amplifier, maximum output voltage is 800 V. A low-voltage input analog signal (0-8 V) with an arbitrary waveform is amplified with 100:1 factor and delivered to a Pockels cell.

QBX-08 contains a fan for active cooling. QBX-08 EO driver can be supplied in built-in and encased versions. Output polarity, gain, load type, maximum output voltage are subject to modifications.

More powerful model QBX-16 (1600V max) is available as a PCB plate.
