42 Operation Theory
NOTE The M_counter defined in Middle-Trigger is different from
that of the Pre-Trigger. In Middle-Trigger, M_Counter
ends counting before the trigger event while in Pre-Trig-
ger, M_Counter ends counting right at or before trigger
event. Refer to Figure 4-6 and Figure 4-9.
Post-Trigger Acquisition
Use post-trigger acquisition in applications where you want to col-
lect data after a trigger event. The number of scans after the trig-
ger is specified in PSC_counter, as illustrated in Figure 4-10. The
total acquired data length = number of enable-channel *
PSC_counter.
