Agilent B2900 SCPI Command Reference, Edition 2 4- 45

Subsystem Commands

:MEASure:<CURRent|RESistance|VOLTage>?

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 item can be set to

CURRent, RESistance, or VOLTage.

Syntax :MEASure:<CURRent[:DC]|RESistance|VOLTage[:DC]>? [chanlist]

For <CURRent[:DC]|RESistance|VOLTage[:DC]>, select CURRent[:DC] for

current measurement, RESistance for resistance measurement, or VOLTage[:DC]

for voltage measurement.

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,ch2curr

This example shows the data containing the current data (ch1curr) of channel 1, and

the current data (ch2curr) 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”.

Example :MEAS:CURR? (@2,1)

1 2 ... 162 163 164 165 166 167 168 169 170 171 172 ... 325 326
