Pre-Acquisition Setup - Image Intensier
EXTERNAL TRIGGER
IOC OPTIONS DESCRIPTION
Pulses per
Trigger
Default:
One pulse per Trigger
Standard mode of operation in external trigger. Every external
trigger will generate only one gate pulse.
Advanced:
Burst pulses per
trigger:
The user can select for multiple pulses per trigger. The external
trigger*generates the rst pulse, subsequent pulses are
generated internally by a user dened Period/Frequency.
Advanced:
Burst/Fit pulses per
Exposure
Software calculates the maximum number of pulses that can t
into the exposure. The external trigger generates the rst pulse,
subsequent pulses are generated internally by a user dened
period/frequency. Any subsequent triggers that arrived within
the exposure time are ignored.
INTERNAL TRIGGER
IOC OPTIONS DESCRIPTION
Pulses per
Exposure
Fit to CCD exposure:
Software calculates the maximum number of pulses that can
t into the exposure. The Fire pulse generates the rst pulse
determined by the delay and width elds, subsequent pulses
are generated internally in the DDG by a user dened period/
frequency.
Burst:
Same as “Fit to CCD exposure” but the user can chose the
number of gate pulses per exposure.
Note: A default minimum of 20 ns delay applies when Integrate on Chip is selected and when the DDG generates the pulse train internally by
a user-dened frequency or period. This is a characteristic of the DDG and it is related to its ability to set the period between pulses in 20 ns
intervals. This delay is in addition to the inherent insertion delay.
