HOW THE PROCESSOR
STORES IMAGES
RECORD TRIGGER
The Processor also treats memory as a circular buffer when using
the RECORD TRIGGER mode. Pictures are stored in sequence with
the current picture replacing the oldest picture in memory so that
you always have the 1637 most recent frames. The trigger input
signal causes the Processor to mark the next frame as frame zero.
The Processor then reads the number of pretrigger frames set
with the TRIG softkey and subtracts that number from the total
number of frames of memory available. The result of this arith-
metic is the number of post trigger frames to be recorded. The
Processor records the calculated number of frames after the
trigger and then stops recording.
If the event you are trying to study is controlled by an electrical
signal or if the condition you are trying to study generates an
electrical signal RECORD TRIGGER is the way to operate the
Motion Analyzer. The trigger signal can cause the Processor to
start a recording, stop a recording, or save x number of frames
before the trigger and y number of frames after the trigger signal.
