Subsystem Commands
:READ[:SCALar]:<CURRent|RESistance|SOURce|STATus|TIME|VOLTage>
?
Example :FORM:ELEM:SENS CURR,SOUR
:READ? (@1,2)
:READ[:SCALar]:<CURRent|RESistance|SOURce|STA
Tus|TIME|VOLTage>?
Executes the :INITiate command and the :FETCh[:SCALar]:<CURRent|
RESistance|SOURce|STATus|TIME|VOLTage>? command in series, and returns the
latest current measurement data, resistance measurement data, source output setting
data, status data, time data, or voltage measurement data specified by CURRent,
RESistance, SOURce, STATus, TIME, or VOLTage. The data is not cleared until the
:INITiate, :MEASure, or :READ command is executed.
Syntax :READ[:SCALar]:<CURRent|RESistance|SOURce|STATus|TIME|VOLTage>?
[chanlist]
For <CURRent|RESistance|SOURce|STATus|TIME|VOLTage>, specify CURRent
for current measurement data, RESistance for resistance measurement data,
SOURce for source output setting data, STATus for status data, TIME for time data,
or VOLTage for voltage measurement data.
Parameter chanlist Channels to return the data. 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 latest data specified by CURRent, RESistance, SOURce,
STATus, TIME, or VOLTage. 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.
ch1curr10,ch2curr5
This example shows the data containing the latest current data (ch1curr10) of the
10-step sweep measurement by channel 1, and the latest current data (ch2curr5) of
the 5-step sweep measurement by channel 2.
