Command reference
Details on all common commands except those associated with the status model
are covered below. See
Appendix D for information on using status commands.
*IDN? — identification query Reads ID information
The identification string includes the manufacturer, model number, serial number,
and firmware revision levels and is sent in the following format:
Keithley Instruments Inc., Model nnnn, xxxxxxx, yyyyy
Where: nnnn is the model number (Model 2601/2602/2611/2612).
xxxxxxx is the serial number.
yyyyy is the firmware revision level.
*OPC — operation complete Sets OPC bit
*OPC? — operation complete query Places a “1” in output queue
When *OPC is sent, the OPC bit in the Standard Event Register (see Appendix D)
will set when all overlapped commands complete. An ASCII “1” is also placed in
the Output Queue to be read by the *OPC? query when overlapped commands
complete.
*RST — reset Return SourceMeter to defaults
When the *RST command is sent, the SourceMeter returns to the default
conditions (see
Table 1-3 on page 1-25).
*TRG — trigger Send remote trigger to SourceMeter
Use the *TRG command to issue a GPIB or RS-232 trigger to the SourceMeter. It
has the same effect as a group execute trigger (GET).
*TST? — self-test query Return 0
This command always places a 0 in the Output Queue. It is included for common
command compatibility, but the Series 2600 does not actually perform a self-test.
