Grab Setup
With Grab Setup the user can set properties on the device such as shutter and gain as
well as illumination properties and thereby control some parameters used for image
acquisition. Grab Setup is basically used to specify how to grab an image. Acquisition tools
such as ‘Grab’, ‘Start Snapshot’ and ‘Ping-Pong Grab’ specify when to grab images and
where the images should be placed.
Grab Setup is often used early on in a program, but can be used more than once if a
parameter has to vary during the program execution.
Input Parameters
01 = Exposure time (us)
This parameter defines how many micro seconds the
shutter is open. Common values for this setting are
4000-25000.
02 = Gain
This parameter sets the gain for the device. Common
values are 300-600 for this parameter.
03 = External trigger
This parameter defines whether the acquisition tools
should be synchronized with an external trigger signal.
04 = Trigger slope
If the
External trigger
parameter is set to true, this
parameter indicates if the synchronization should be on
a rising or falling flank of the external trigger signal.
05 = Strobe enable
If a trigged source of illumination is used, this parame-
ter should be set true.
06 = Strobe time (us)
If the
Strobe enable
parameter is set true this parame-
ter specifies the duration of each strobe flash in micro-
seconds. Allowed values are 10–400.000 us.
Returned Values
None
