A Differential Discriminator for bh TCSPC Modules

The DIFDIS module is a differential-input discriminator for SPC-150N, SPC-150NX, and SPC-150NXX and SPC-160 TCSPC modules. It is used in combination with detectors the photon pulses of which have no or negligible amplitude jitter, such as SPAD modules or SSPD detectors. In these cases, the DIFFDIS module offers increased flexibility in terms of input pulse polarity, improved immunity against synchronous-noise pickup, and superior differential nonlinearity of the TCSPC measurement. The DIFDIS module is a direct replacement for the standard constant-fraction discriminator (CFD) module.
