Operation complete and query: *OPC and *OPC?
Wait for pending overlapped commands to complete.
*OPC
Operation complete command that sets the OPC bit
*OPC?
Operation complete query that places a "
1
" in the output queue
When
*OPC
is sent, the OPC bit in the Standard Event Register (see
(on page 5-12, on
page E-1)) is set when all overlapped commands complete. The
*OPC?
command places an ASCII
"
1
" in the output queue when all previous overlapped commands complete.
Reset: *RST
Returns the instrument to default conditions.
*RST
Command that returns the instrument to default conditions
When the
*RST
command is sent, the instrument returns to the default conditions. This performs the
(on page 7-159).
Self-test query: *TST?
Requests self-test results.
*TST?
Places a zero (
0
) in the output queue
This command always places a zero (
0
) in the output queue. This command is included for common
command compatibility only; the 2606B does not actually perform a self-test.
Trigger: *TRG
Generates a command interface trigger event for the trigger model.
*TRG
This command generates the
trigger.EVENT_ID
trigger event for the trigger model
The
trigger.EVENT_ID
is a constant that contains the command interface trigger event number.
You can set the stimulus of any trigger object to the value of this constant to have the trigger object
respond to the trigger events generated by this command. See
(on page 7-346)
Using the remote trigger model
(on page 3-33).
Wait-to-continue: *WAI
Suspends the execution of subsequent commands until all previous overlapped commands are
finished.
*WAI
This pauses until overlapped commands are complete
Two types of device commands exist:
•
Overlapped commands.
Commands that allow the execution of subsequent commands while
instrument operations of the overlapped command are still in progress.
•
Sequential commands.
Commands whose operations finish before the next command is
executed.
The
*WAI
command suspends the execution of subsequent commands until the instrument
operations of all previous overlapped commands are finished. The
*WAI
command is not needed for
sequential commands.
