Bulb Shutter Trigger Mode

In bulb shutter mode, the camera starts exposure from the external trigger edge. Exposure time is equal to the low
state time of the external trigger input. For information about maximum frame rates while triggering, see
Frame Rates When
To configure trigger delay, see
signal and exposure is 45 ns.
Values for Frame Overhead Time and Readout Rate vary by current
Output mode , as follows:
Sensor Input Clock Speed (MHz) Frame Overhead Time (µs) Readout Rate (µs/line)
Sensor Input Clock Speed (MHz) Frame Overhead Time (µs) Readout Rate (µs/line)
