Master Pulse - Hamamatsu Photonics ORCA-Fire C16240-20UP Instruction Manual

Digital CMOS Camera C16240-20UP / C16240-20UP01 Instruction manual_Ver.1.3

11-5 MASTER PULSE

The camera has master pulse function which can generate pulses that is independent of the exposure
or readout timing of image sensor. External trigger mode can work synchronized with the timing pulses
that the master pulse generates, except for External trigger mode in Lightsheet Readout Mode. The
master pulse can be set as a reference signal of the programmable timing output, so it is possible to set
up a synchronous system with peripheral devices without external pulse generator.
This function can be turned ON and OFF. (Default is OFF)
The master pulse supports free running mode, start trigger mode and burst mode. The range of interval
time is 5 µs to 10 s, and the step is 1 µs for the master pulse.
(1) Free running mode
The camera generates pulses inside of the camera during the master pulse is ON.

(2) Start trigger mode
The camera starts generating pulses inside of the camera by input trigger signal.

(3) Burst mode
The camera starts generating pulses inside of the camera by input trigger signal, and the camera
stops generating pulses after the specified number of pulses are generated. And then, the camera
will be ready for the next input trigger signal.
