The device is designed to operate Avalanche photodiodes (APDs) via a gated quenching circuit, capable of functioning at a duty ratio of 10 to 100% within the frequency range of 1 to 10 MHz.
Its primary use is to verify the operation of the APD in Geiger mode and to evaluate the efficiency of light detection. It is also capable of applying a high voltage, adjustable between 0 and 200V, to the optical sensor.
The system requires an input power of 5V, with signal outputs that are observable through an oscilloscope. It is configured to operate TO-5 packaged optical sensors, and a separate dummy mount allows for the operation of other packaged optical sensors.
