The SIB332 sensor interface board provides the electrical and mechanical connectivity between a Hamamatsu S8550 series 4 x 8 element APD array and a Vertilon PhotoniQ multi-channel DAQ system. The S8550 mounts directly to the SIB332 where electrical connections to the 32 APD anodes are routed to a micro-coaxial cable assembly that connects the APD outputs to the PhotoniQ. The negative high voltage bias to the APD array is made through a separate dedicated connector that connects to the high voltage output from the PhotoniQ. Also available on the SIB332 are two outputs that are used in conjunction with the APD array’s common cathode current signal — an amplified version of the signal and a pulse discriminator trigger output.
