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 18-72.) Use the :CURRent:MODE or VOLT-
age:MODE command to select the SWEep sourcing mode. (See “Select sourcing
mode,” page 18-73.) The trigger count is set using the TRIGger:COUNt command.
(See “TRIGger subsystem,” page 18-116.)
RANGing <name>
: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
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 pres-
ently 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.
