Triggering

Goldeye G/CL Technical Manual V4.1.1
Trigger rules
1. The
end of exposure
always triggers the next Readout.
2. The
end of exposure
must always end after the current Readout.
3. The
start of exposure
must always correspond with the Interline Time if Read-
out is true.
4.
Exposure start delay
is equal to the Readout time less the Registered Exposure
Time.
Triggering during the Idle state
For applications requiring the shortest possible trigger latency and the smallest
possible trigger jitter the user trigger signal should be applied when Imaging is
Trigger latency
Time delay between the user trigger and the start of
exposure.
Trigger jitter
Error in the trigger latency time.
Trigger ready
Indicates to the user that the camera is ready to accept
the next trigger.
Registered exposure
time
Exposure time value currently stored in the camera
memory.
Exposure start delay
Registered Exposure Time subtracted from the Readout
time. Exposure start delay indicates when the next
exposure cycle can begin such that the exposure end
after the current Readout.
Interline time
Time between sensor row readout cycles.
Imaging
High when the camera image sensor is either exposing
and/or reading out data.
Idle
High if the camera image sensor is not exposing and/or
reading out data.
Minimum user trigger pulse width
The user trigger pulse width should be at least three times the width of the trigger
latency.
