User_Manual-PILATUS-V1_2.doc 54/57
13.3 External Multi Trigger mode
External multi trigger mode is started with the command “extMtrigger
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.
After issuing the “extMtrigger imagename.tif” command the detector will
monitor and take a number of images defined below, on the level of the trigger
pulse.
The settings that are necessary for external multi triggering are:
• ni
• expt
• delay (optional)
After receiving a trigger on the positive edge, the detector will wait a period of
time defined by “delay”, take exposures defined by “ni” of length “expt”,
readout the images and will rearm to take another images.
The image number is only incremented during the exposure series;
if you reissue the command “extt imagename.tif” it will start writing images
from “imagename_00001.tif” and overwrite existing data.
Wait time ???
13.4 External Enable mode
External enable mode is started with the command “exte 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.
After issuing the “exte imagename.tif” command the detector will monitor and
take a number of images defined by ni gated on the level of the trigger pulse.
Variables “delay”, “expt”, “expp”, etc. are not used in external enable
mode.
The image number is only incremented during the exposure series;
if you reissue the command “extt imagename.tif” it will start writing images
from “imagename_00001.tif” and overwrite existing data.
