The PMS-300, the PMS-400 and the PMS-400A are PC plug in boards with two fast gated photon counting and multiscaler channels. The PMS counts all pulses with an amplitude greater than a selectable discriminator threshold and stores the results into subsequent locations of the memory. The inputs can be gated to count pulses either inside or outside an externally applied gating pulse. Applications are gated photon counting and luminescence-decay and phosphorescence decay experiments in the microsecond and millisecond range.
