In order to avoid trade-offs at maximum frame rate use either the Busy
Status signal or make sure that the external trigger rate follows this
condition:
External Trigger Rate ≤ fmax / 1.001
[External Exp. Ctrl] An external signal applied at BNC #1 (6.6), controls the
start and the duration of the exposure.
A new exposure is started by the falling or rising edge of the voltage
signal at the BNC input. The exposure is finished when the opposite
edge is detected. Thus in this mode, the start as well as the length of the
exposure time can be controlled.
No further settings can be made, as the image timing is completely
controlled by the external trigger signal.
Be aware, that the externally controlled exposure time is limited. The
integration will be stopped automatically if the maximum exposure time
is achieved.
