The trigger delay is a few µs. The minimum pulse duration is 1µs. The edge of trigger is pro-
grammable. The source of trigger is selectable between CameraLink CC1 signal and TTL/IO
trigger input. The period is defined by readout time + programmable shutter time + readout time
+ wait. Therefore the minimum period is 2 × readout time.

Triggered Mode without Full Reset
Principle: An external trigger starts the snap and readout of a frame, without resetting the sen-
sor. The integration time is defined by readout time (+ programmable shutter time, when used).
The trigger event initiates the following sequence:
• Stop of readout frame in progress and reset of readout pointer to line 1
• Shutter output signal is activated during a time programmable within 0 to Tsh range by step
of T1
• Readout of frame N. The readout data is forwarded to the CameraLink interface (FVAL
active) starting with the first line
• Readout of dummy frames (to prevent against large dark current integration) while the
camera waits for the next trigger event
The trigger delay is a few µ s. The minimum pulse duration is 1µs. The edge of trigger is pro-
grammable. The source of trigger is selectable between CameraLink CC1 signal and TTL_IO
trigger input. The period is defined by the programmable shutter time + readout time + wait.
