Trigger Modes
Auto Sequence:
the camera optimizes the image recording to
achieve the best possible frame rate.
In the
Auto Sequence
mode, the camera achieves the fastest
possible frame rate depending on the adjusted exposure time
and the required readout time.
Upon a start command images are recorded until a stop
command.
Software Trigger: single images are recorded by this Camware
command. The single image is acquired by pressing the Single
Trigger button. This button appears after pressing the Start
Record button (see
6.4
). Other signals have no influence on this
operating mode.
External Exposure Start:
image acquisition is triggered by an
external signal. The single trigger button acquires a single
image for a test.
In the
External Exp. Start
exposure control mode, single
image acquisition is started by the rising / falling edge of the voltage
signal at the BNC input (see appendix A1.3, A2 ).

Exposure Time and time-base
ITime-base may be changed from automatic to µs or ms. If
your input is out of the range of the camera, it will be
automatically changed to the nearest possible setting. The
current frame rate (fps) is always displayed. The exposure time
(delay time setting is not available for pco.ultraviolet) can be set
in steps of 1
μ
s. The jitter of the actual exposure start edge: <
13 ns.
