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
Status model
(on page 5-14, 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
same actions as
reset()
(on page 7-160).
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 Series 2600B 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
trigger.EVENT_ID
(on page 7-342)
and
Using the remote trigger model
(on page 3-34).
