EXT
SYNC
The EXT SYNC or external synchronization function permits the
EKTAPRO EM Motion Analyzer to operate asynchronously. This
means that the start time of each picture recorded is controlled
by a "true" transition at the EXT SYNC IN connection on the rear
panel of the Processor.
One picture will be recorded for each EXT SYNC signal transition.
For full frame pictures the maximum repetition rate for the
synchronizing signal is 1,000 pulses per second. If you are using
split frames the maximum repetition rate for the synchronizing
signal is 6,000 pulses per second. In the EXT SYNC mode, repeti-
tion rates greater than 6,000 pulses per second are too fast for
the processor electronics to handle. Trying to run the processor
at over 6,000 pulses per second will result in scrambled images
when playing back that recording.
The sensor is always gathering light, so as the time between
picture readouts get longer, image quality will tend to degrade.
Image quality is still reasonably good with a synchronizing signal
repetition rate of 10 pulses per second.
When EXT SYNC is on the REC RATE and EXP softkey windows
will show NA, and the REC TIME readout in the keypad message
field will be blank.
Press the EXT SYNC softkey and
ON
then use the arrow keys to
select ON or OFF .
