Models 2500 and 2502 User’s Manual SCPI Signal-Oriented Measurement Commands 16-5
MEASure[:CURRent[:DC]]?
Parameters CURRent[:DC] Amps function
Description This command combines other signal-oriented measurement commands
to perform a “one-shot” measurement and acquire the reading.
When this command is sent, the following commands execute in the
order that they are presented.
• :CONFigure:CURRent[:DC]
• :READ?
When :CONFigure is executed, the instrument goes into a one-shot
measurement mode. See “CONFigure:CURRent[:DC]” for more
details.
NOTE :MEAS? is illegal when the :ARM:SOUR BUS command is in effect. See
Section 10, “Triggering,” for 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?,” page 16-4, for more
details.
NOTE The :FORM:ELEM command controls the reading source. To access channel 1
readings, send :FORM:ELEM CURR1 before sending :MEAS?. To access chan-
nel 2 readings, send :FORM:ELEM CURR2 before using :MEAS?.
When :MEASure? is sent, the source turns on and a single measurement
is performed. If auto output-off is enabled (:SOURce1:CLEar:AUTO
ON or :SOURce2:CLEar:AUTO ON), then the corresponding output
will turn off after the measurement is completed. If auto output-off is
disabled (:SOURce1:CLEar:AUTO OFF or :SOURce2:CLEar:AUTO
OFF), then the corresponding output will remain on after the measure-
ment is completed.
WARNING With auto output-off disabled, the output will remain on after the one-
shot source-measure operation is performed. Beware of hazardous
voltage that may be present on the output terminals.
