Subsystem Commands
:MEASure?
MEASure Subsystem
:MEASure?
Executes a spot measurement (one-shot measurement) and returns the measurement
result data. Measurement conditions must be set by SCPI commands or front panel
operation before executing this command. Measurement items can be selected by
the
:FORMat:ELEMents:SENSe command.
Syntax :MEASure? [chanlist]
Parameter chanlist Channels to perform measurement. Parameter data type is
channel list. (@1)|(@2)|(@1,2)|(@1:2)|(@2,1)|(@2:1). See
“Channel List Parameter” on page 1-8.
(@1) selects channel 1 only. (@2) selects channel 2 only. (@1,2), (@1:2), (@2,1),
and (@2:1) selects both channels 1 and 2.
If this parameter is not specified, chanlist=(@1) is set.
Query response response <newline>
response returns the measurement result data. Response data type is NR3. See “Data
Output Format” on page 1-12.
If both channels 1 and 2 are selected by chanlist, response returns the channel 1 data
and the channel 2 data in this order. See the following example. With the ASCII data
output format, each data is separated by a comma.
ch1curr,ch1sour,ch2curr,ch2sour
This example shows the data containing the current data (ch1curr) and source data
(ch1sour) of channel 1, and the current data (ch2curr) and source data (ch2sour) of
channel 2.
If the measurement function is not enabled or no data exists, response returns
+9.910000E+37 (ASCII) or NaN (IEEE-754) which indicates “not a number”.
