The PCOUNT G is a GATED 1 GHz/Channel photon counter that has the ability to count continuously OR select photon count times when the external gate input is positive.    The external input gate repetition rate can be above 200 Megahertz.  Photon events are collected into a user chosen number of bins.

The PCOUNT G can have one, two, or three channels of 1 GHz/second photon counting with one additional channel for the fiducial marking of gate edges.   The gate intervals do NOT have to be the same width throughout a collection cycle.    The gate width can be monitored in the un-gated mode as well as the gated mode on the back of the device.

Each and every gate interval can be individually examined for Time Correlated Photon events.   
The number of photons can be summed over any part of a gate or all of the gate times.  The PCOUNT G can also collect photons in the un-gated mode. The gate input level is 1.1V to 3.3V with an adjustable threshold.  

The PCOUNT G hardware begins accepting photons continuously once triggered - subject to software control and/or gating.  The trigger can be provided by an external SMA input, a push-button,  or switch latch after a manual reset to synchronize channels.  Photon Counting disk storage begins under software control.

The PCOUNT G is designed for EDGE detection of photons from the PV16 amplifier discriminator with 100 pico-second minimum photon widths.   
The back of the PCOUNT G provides + and - input gate echos, gated GHz clock output, gated 125 MHz clock, and trigger indication.
