7. TIMING PCO.DICAM C4
The following chapter assumes that you have carefully read the
previous chapters about Single and Double Image mode timing of a
single pco.dicam C1 (chapter
6 ).
7.1 MASTER VS INDIVIDUAL CHANNEL TRIGGER
The pco.dicam C4 allows external triggering on the rear panel (see
A2.4 ) in two different ways, which will be explained below.
See chapter HARDWARE I/O CONTROL PCO.DICAM C4 8.5 to
select the
Master Trigger
or
Channel Trigger
mode.
Master Trigger
The camera consists of four individual channels that can be
configured and triggered completely independently of each other. For
the typical application, however, it is much more convenient to
synchronize all channels internally and to control them via a common
Master Trigger .
Note, the use of the
Master Trigger
causes an additional latency
period of 10 ns electrically, or optically 15 ns which has to be added
to the intrinsic delay (see
6.1 , 6.2 )
In order to activate the
Master Trigger , in pco.camware in Camera
Properties under Timing the Trigger Mode Ext. Exp. Start must be
selected, see 8.1.
Operating Modes
•
If you want to work with constant exposure time and frame rates:
use
Common Time Properties see 9.1 and Master Trigger .
•
In case you want to record with different exposure times and / or
non-sequential or different channel order, you cannot use the
Common Settings of Common Time Properties . For triggering
the Master Trigger or the four individual channel triggers can be
used.
Individual Channel Trigger
For single triggering, a BNC
socket (plus arm socket for
double image operation) is
available on each channel for
electrical triggering.
For individual channel
triggering, the latency time is
minimal; compare to the final
data sheet of your camera.
Note that no optical input is available for the individual
Channel
Trigger unlike the Master Trigger !
