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”.
