6.4.7. Sensor Gate Control

This function is for applications with strobe flash illuminations or long time accumulations up to several frames. The resulting video is then read out after the first FVAL (or SG), following the trailing edge of the Sensor Gate Control signal.

The sensor gate control signal can be synchronized by the FVAL signal. Fig. 29A. and fig. 29B. shows the minimum sensor gate signal width if it is synchronized to FVAL.

To use this mode:

 

 

 

Set function:

 

 

Trigger mode “Normal”
