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 mode. Use the :CURRent:MODE or VOLTage:MODE command to select the
SWEep sourcing mode. See Select sourcing mode. The trigger count is set using the
TRIGger:COUNt command. See Trigger subsystem.

:SOURce[1]:SWEep:RANGing <name> Select source ranging mode
Parameters <name> = BEST Use the best fixed mode
AUTO Use the most sensitive source range for
each sweep level

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 opera-
tion, 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.

ear scale. With LOGarithmic selected, the source-measure points will be
performed on a logarithmic scale.
