Advanced SCPI Operations 8-11
diagram shows that the 1256 must be armed before it responds to
triggers. Once it is armed, it remains armed and sequences
through the scan list until the number of triggers equal to the
trigger count is received. After that, it is disarmed and must be
rearmed again. The 1256 may also be manually disarmed with the
ABORT command.
Figure 8-1, State Transition Diagram For Arming and Triggering the 1256
Generating a Single
Trigger
The 1256 may be armed, and a single trigger may be sent, using
the TRIGGER:IMMEDIATE command. The syntax for this
command is:
:TRIGger
[:SEQuence]
:IMMediate
This command is equivalent to the following:
A)
Programming the trigger source
B)
Arming the 1256 with an INIT:IMMEDIATE command
C)
Sending a single trigger on the selected trigger source
