17-54 SCPI Command Reference
SENSe1 subsystem
The Sense1 subsystem is used to con fi gure and control the measurement functions of the
SourceMeter. Many of the commands are global, where a single command affects all functions.
Some commands are unique to a speci
fi c function. For example, you can program a unique
range setting for each basic function (amps, volts, and ohms).
A function does not have to be selected before you can program its various con fi gurations.
Whenever a programmed function is selected, it assumes the programmed states.
The commands for this subsystem are summarized in Table 17-5.
Select measurement functions
:CONCurrent <b>
[:SENSe[1]]:FUNCtion:CONCurrent <b> Control concurrent measurements
Parameters
<b> = 0 or OFF Disable concurrent measurements
1 or ON Enable concurrent measurements
Query
:CONCurrent? Query state of concurrent measurements
Description
This command is used to enable or disable the ability of the instrument to
measure more than one function simultaneously. When enabled, the instru-
ment will measure the functions that are selected. See [:ON], :OFF and
:ALL.
When disabled, only one measurement function can be enabled. When mak-
ing the transition from :CONCurrent ON to :CONCurrent OFF, the voltage
(VOLT:DC) measurement function will be selected. All other measurement
functions will be disabled. Use the :FUNCTion[:ON] command to select
one of the other measurement functions.
[:ON] <function list>
:OFF <function list>
[:SENSe[1]]:FUNCtion[:ON] <function list> Specify functions to be enabled
[:SENSe[1]]:FUNCtion:OFF <function list> Specify functions to be disabled
Parameters
<function list> = “ CURRent[:DC] ” Amps measurement function
“ VOLTage[:DC] ” Volts measurement function
“ RESistance ” Ohms measurement function
NOTE Each function in the list must be enclosed in quotes (double or single) and separated
by a comma (i.e., :func:on “volt”, “curr”).
