2.1 Description of Counting Process
Pulses detected on Channel 1, Channel 2, and the optional Gate channel will be counted as
coincident pulses based on a number of settings made prior to the measurements. In general,
the simplest measurement of coincidence is as shown in Figure 7:
Figure 7. Simple coincidence measurement described.
Two pulses will be counted by the CC1 to be coincident if:
a. The time between the rising edges of the two pulses is less than the coincidence window
If the GATE signal is enabled, then the two pulses will only be counted by the CC1 as coincident
if the following two conditions are satisfied:
a. The time between the rising edges of the two pulses is less than the coincidence window
b. The GATE signal is enabled during both rising edges
Figure 8 represents a coincidence measurement with the GATE signal enabled.
