Variables Description
nexpf Number of exposures per frame
This is a so called multi exposure mode. nexpf sets the
number of exposures before the detector is read out
e.g. “nexpf 3” exposes the detector 3 times before
reading out an image of the 3 combined exposures.
13.2 External Trigger mode
External trigger mode is started with the command “extt imagename.tif” where
imagename.tif is the name of the images you wish to be taken. The image
name will be “imagename_00001.tif”. If ni > 1 the image number will be
incremented for each image in the series.
The settings that are necessary for external triggering are:
• ni
• expt
• expp
• delay (optional)
After receiving a trigger on the positive edge, the module will wait a period of
time defined by “delay”, take an exposure of length “expt”, readout the image
and after a period defined by “expp” will repeat the cycle for “ni” images.
The image number is only incremented during the trigger mode, if
you reissue the command “extt imagename.tif” the system will start writing
images from “imagename_00001.tif” and overwrite existing data.
