DESCRIPTION
The Trigger On (
@
) command will start or stop the acquisition accordingly when the
start
or
stop
arguments
of the Set Trigger Configuration (
T
) command is set to
1
(trigger on). The
T
command is used as a trigger
source and follows the same rules as other trigger sources as defined by the
T
command. The
@
command is
valid only when an acquisition is configured where either the start and/or stop event is defined as the Trigger On
command. If this command is issued when the acquisition is not configured for stop and/or start Trigger On
command, an error condition will occur.

trigger being Trigger On command
PRINT#1, “OUTPUT07; @X”
‘ Start the acquisition
SLEEP 10
