User’s Manual SCPI Signal Oriented Measurement Commands 17-5
Note that if auto output-off is disabled (:SOURce1:CLEar:AUTO
OFF), then the output must be turned on before you can perform
a :READ?. The output will then remain on after all source-
measure operations are completed.
If auto output-off is enabled (:SOURce1:CLEar:AUTO ON), then
the output will automatically turn on at the beginning of each SDM
(source-delay-measure) cycle and turn off after each
measurement.
NOTE For the Model 2430 Pulse Mode, the output will turn on when the
:READ? command is sent.
See Appendix C, “Data Flow,” for a detailed explanation on how data
flows through the various operation blocks of the SourceMeter. It clarifies
the type of readings that are acquired by the various commands to read
data.
:MEASure[:<function>]?
Parameters <function> = CURRent[:DC]Amps function
VOLTage[:DC]Volts function
RESistanceOhms function
Description This command combines other signal oriented measurement
commands to perform a “one-shot” measurement and acquire the
reading. Note that if a function is not specified, the measurement
will be done on the function that is presently selected.
When this command is sent, the following commands execute in
the order that they are presented.
• :CONFigure:<function>
•:READ?
When :CONFigure is executed, the instrument goes into a “one-
shot” measurement mode. See :CONFigure for more details.
When :READ? is executed, its operations will then be performed.
In general, another :ABORt is performed, then an :INITiate, and
finally a FETCh? to acquire the readings. See :READ? for more
details.
When :MEASure? is sent, the source turns on and a single
measurement is performed. If auto output-off is enabled
(:SOURce1:CLEar:AUTO ON), then the output will turn off after
the measurement is completed. If auto output-off is disabled
(:SOURce1:CLEar:AUTO OFF), then the output will remain on
after the measurement is completed.
