11-1-7 TIMING OUTPUT
The camera provides a range of trigger output signals to synchronize with an external instrument and
the camera becomes the master and the external instrument becomes the slave.
There are four different trigger output functions as follows.
- Global exposure timing output
- Any low exposure timing output
- Programmable timing output
- Trigger ready output
Also, it can output continuous High output (High output fixed) or continuous Low output (Low output
fixed). They are output from trigger output connector.
(1) Global exposure timing output
It shows the global exposure timing where all lines expose at the same time. There is a case that
one event is divided into two frames because the timing of the exposure in each line is different
for the rolling shutter. However, by using the Global exposure timing output the global exposure
becomes possible for the phenomenon that happens for this period. Global exposure timing output
shows the period where all lines expose at the same time.
•
There is no output signal when the exposure time is less than the frame rate.
(2) Any row exposure timing output
Global exposure timing output shows the global exposure timing where all lines expose at the
same time. While the any row exposure timing shows when any of the rows.
(3) Programmable timing output
By using the programmable timing output, synchronizing external devices is simple. A system that
needs simple timing signal does not require a delay unit or pulse generator. It is possible to
program and output a pulse that has an optional pulse width and an optional delay time to Read
End (the end of readout timing), Vsync or Input trigger signal. The setting range for delay time is
0 µs to 10 s, and the setting range for pulse width is 1 µs to 10 s.
The relation between the parameter which can be set with each reference signal, and an output
signal becomes below.
Reference signal
Output signal
Read End
The signal with the preset pulse width is output after the preset delay from the
end of the sensor readout.
Vsync
The signal with the preset pulse width is output after the preset delay from the
start of the sensor readout.
Input trigger signal The signal with the preset pulse width is output after the preset delay from the
input signal.
