Specify number of additional times trigger executes
Note: You cannot use the legacy interface on 64-bit MATLAB®. See About the Session-Based Interface to acquire and generate data on a 64-bit MATLAB.
You can configure a trigger to occur once (one-shot acquisition)
or multiple times. If
TriggerRepeat is set to its
default value of zero, then the trigger executes once. If
set to a positive integer value, then the trigger executes once, and
is repeated the specified number of times. For example, if the value
is set to 2, you will get a total of 3 triggers. If
inf then the trigger executes continuously
stop function is issued or an error occurs.
You can quickly evaluate how many triggers have executed by
TriggersExecuted property or by invoking
the display summary for the device object. The display summary is
invoked by typing the device object name at the MATLAB Command
We have observed that National Instruments USB devices have
a significant cycle time for the communications required to trigger
the device. If you are using an NI USB device, we recommend that you
set up longer acquisitions that use fewer triggers. That is, increase
