A3 ADAPTER / ACCESSORIES
A3.1 PCO.TRIGGER UNIT
The pco.trigger unit is optional for
pco.dicam C1 and a standard
accessory for pco.dicam C4.
With the help of this trigger unit,
clear trigger signals for the camera
can be generated and adjusted from
your input signals.
First put power switch to
on and
select the desired main function with
the
Central Tuning Knob
.
Input Connectors
Comparator in
If there are spurious signals on the trigger line, then the comparator
can be used to define a higher threshold for the trigger by adjusting
the
Level knob (-0.5 V … 15 V). The reverse application is also
possible: the camera is triggered by even the smallest voltage pulses.
The Comparator Input can be used to generate proper TTL trigger
signal.
Input: BNC Comparator 0 … 24 V
TTL in
TTL in is used to convert electrical TTL trigger signals to optical
signals. For many experiments in the high-energy field, the optical
triggering of the camera is necessary e.g. for signal protection and /
or range extension. Define whether you want to use the falling or
rising edge of the input TTL signal with the
Central Tuning Knob .
Input:
BNC TTL in 0 … 5 V
Photodiode in
For fast continuous processes, it is sometimes only important that the
camera records in synchronization with pulsed lighting (flash, etc.). To
generate the necessary trigger signal for the camera, a photodiode at
the location of the experiment is the simplest method. The anode of
the photodiode is to be connected to the screen of the BNC socket,
the cathode to the inner conductor.
Adjust the trigger threshold with
Sensitivity
knob.
7 Hz Test
Generation of external trigger signals with 7 Hz repetition frequency
for test purposes.
To be used to verify the functionality of the cameras trigger input or
during experimental setup.
