Using SCPI commands:
To receive the name of one source configuration list stored on the instrument, use the following
command.
:SOURce:CONFigure:LIST:CATalog?
For a measure configuration list, replace :SOURce with :SENSe.
Each time this command executes, the name of one defined configuration is returned. Keep sending
this command until it returns an empty string to get all defined lists. After the command returns an
empty string, it wraps around and starts returning names again. If only an empty string is returned, no
configuration lists of the specified type exist.
Using TSP commands:
To receive the name of one source configuration list stored on the instrument, use the following
command.
print(smu.source.configlist.catalog())
For a measure configuration list, replace source with measure.
Each time this command executes, the name of one defined configuration is returned. Keep sending
this command until it returns nil to get all defined lists. After the command returns nil, it wraps
around and starts returning names again. If only nil is returned, no configuration lists of the specified
type exist.
Determining the size of a configuration list
You can view the number of configuration points that are in a specific configuration list.
Using SCPI commands:
To view the number of configuration points in a source configuration list named MyConfigList,
send the following command:
:SOURce:CONFiguration:LIST:SIZE? "MyConfigList"
For a measure configuration list, replace :SOURce with :SENSe.
Using TSP commands:
To view the number of configuration points in a source configuration list named MyConfigList,
send the following command:
smu.source.configlist.size("MyConfigList")
For a measure configuration list, replace source with measure.
Saving a configuration list
Configuration lists are lost when you turn the instrument off and turn it on again. Save a configuration
list by creating a configuration script (TSP or front panel) or using the *SAV and *RCL commands
(SCPI). A configuration script saves the settings of the instrument, including all defined source and
measure configuration lists. See Saving setups (on page 2-112) for additional information.
