Sensor Gate Control - JAI CV-M 9CL Operation Manual

6.4.7. Sensor Gate Control

This function is for applications with strobe flash illuminations or long time accumulations up to
several frames. The external Sensor Gate control signal will disable the internal SG pulse so the
accumulation will continue during the next frame. As long as the sensor gate control signal is
low, the accumulation will continue. The resulting video is read out after the first FVAL (or SG),
following the trailing edge of the Sensor Gate Control signal. Fig. 28.
To disable the internal SG pulse, the sensor gate control signal should be low 2 µs before.
Fig. 29. shows the sensor gate signal setup time and hold time. It is inside the first line after
FVAL goes low.
For timing details, refer to fig. 13. through fig. 20. and fig. 28. - 29.

Important notes on using this mode
Minimum setup and hold time for external sensor gate control signal is shown in relation to the first LVAL after FVAL
falling edge.
