4.2.4.1 Framerates of master and slave camera
If you synchronize a slave camera by a master camera, then the framerate of the slave
camera must be slightly above the master camera’s frame rate (as mentioned before),
otherwise the slave camera will not provide the same framerate as the master camera.
Example:
You want to record with 1000 frames per second. Adjust the master camera to the de-
sired 1000 fps, select 1004 fps for the slave camera. Then the slave camera will deliver
the master camera’s framerate (1000 fps)!
L
If “Sync in” is enabled and no “sync in” signal is provided, the camera will not
record and timeout will occur!
The framerate of the slave camera must be slightly above the master camera’s
frame rate:
Slave camera should be set up to framrate that is at least 2 fps higher than the
master’s framerate for Cube1 and Cube2 models and at least 20 fps higher for
Cube3 models.
Thus the maximal achievable real framerate will be about 2480 fps @ full
image resolution (512 * 512) for Cube3
slave cameras
4.2.5 Enable IRIG-B input
If the camera was deliverd with the option IRIG-B, the processing of the IRIG-B input
signal may be activated with the check box “Enable IRIG-B”. See chapter IRIG-B input
for details.
After activation, the signal will be processed in the following manner:
-
decoding of the modulated 1KHz time code that is typically derived from a GPS
receiver.
-
The time code will be displayed in the info line as day of the year and time of
day (GMT) in the following format:
ttt hh:mm:ss, whereas
ttt = day of the year
hh = hour
mm = minute
ss = second.
-
The internal frame rate timebase is then synchronized once per second to the
IRIG-B 1sec marker, and therefore phase aligned to the 1KHz IRIG-B signal.
