3.24. IRIG-sync Operation
This camera system supports IRIG-sync operation, in which the sensor drive signal is synchronized
with the input of IRIG-B signal.
How IRIG-sync operation works?
In IRIG-sync operation, the image sensor is driven by the timing signal shown below. Exposure to the
sensor ends at the start of the IRIG-1PPS signal
IRIG-B : IRIG code that is input to the camera
IEIG-1PPS : 1PPS timing of the IRIG code
EXPOSURE : Exposure to the camera sensor (exposure is indicated by high duration)
CAM_V
: Camera’s vertical sync signal
 For the settig about the function, refer to the "Photron FASTCAM Viewer User's Manual" or the
"LCD Remote Controller User's Manual".
