6.1.5. Sensor Gate Control

This function is for applications where a strobe flash is the only illumination, and where the exact time for the strobe firing is not known. The time window for the strobe firing can be up to several frames. The resulting video read out can also be delayed by this function. It makes the synchronization of the frame grabber more flexible.

The Sensor Gate Control signal will inhibit the internal SG signal so the accumulation can continue. The sensor gate control signal can be synchronized by the FVAL signal.

This function will only work in normal continuous mode. TR=0. The function is on if SG=1. The SG signal is an internal signal, which is low when the accumulated charge on the photo diode array is transferred to the vertical ccd registers for read out.

When the Sensor Gate Control input is high, the internal SG pulse is inhibited, and the signal accumulation on the photo diode array can take place. When the strobe flash is fired, the Sensor Gate Control signal can be low. The resulting video is then read out after the first FVAL (or SG), following the falling edge of Sensor Gate Control signal.
