Configure voltage and current sweeps
There are two methods to configure the start and stop levels of a sweep. You can use either
the :STARt and :STOP commands or you can use the :CENTer and :SPAN commands.
NOTE In order to run a sweep, the selected source must be in the sweep sourcing mode
and the trigger count should be the same as the number of source-measure
points in the sweep.
Use the :FUNCtion:MODE command to select the current or voltage source function. (See
“Select function modes,” page 18-73.) Use the :CURRent:MODE or VOLTage:MODE
command to select the SWEep sourcing mode. (See “Select sourcing mode,” page 18-74.)
The trigger count is set using the TRIGger:COUNt command. (See “TRIGger subsystem,”
page 18-120.)

:SOURce[1]:SWEep:RANGing <name> Select source ranging mode
Parameters <name> = BEST Use the best fixed mode

each sweep level
FIXed Use the present source range for the
entire sweep
Query :RANGing? Query source ranging mode
Description This command is used to select the source ranging mode for sweeps.
With BEST selected, the SourceMeter will select a single fixed source
range that will accommodate all the source levels in the sweep. For front
panel operation, this is the BEST FIXED option.
With AUTO selected, the SourceMeter will automatically go to the most
sensitive source range for each source level in the sweep. For front panel
operation, this is the AUTO RANGE option.
With FIXed selected, the source remains on the range that it is presently
on when the sweep is started. For sweep points that exceed the source
range capability, the source will output the maximum level for that
range. For front panel operation, this is the FIXED option.
