Princeton Instruments PI-MAX2 System - Figure 61. DG535: External Sync, Preopen, Exposure Time = 0 Sec

110 PI-MAX/PI-MAX2 System Manual Version 5.F
The timing diagrams below show the sequence of events for a 0 second exposure time
and for an exposure time greater than 0 seconds. When the exposure time is set to 0
seconds (Acquisition|Experiment Setup…|Main) and External Sync PreOpen is
selected, the gating determines the actual time (t
exp
) that the array will be exposed to
incoming signal.
Figure 61. DG535: External Sync, PreOpen, Exposure Time = 0 sec.
When the exposure time is set to something other than 0 (Acquisition|Experiment
Setup…|Main) and External Sync PreOpen is selected, the start of the exposure time is
controlled by the External Sync trigger, and one or more gates may occur during the
exposure time depending on the gating parameters set up for the DG535
(Setup|Pulsers…|DG535).
