DIRection <name>
:SOURce[1]:SWEep:DIRection <name>Set direction of source 1 sweep
:SOURce2:SWEep:DIRection <name>Set direction of source 2 sweep
Parameters <name> = UP Run sweep from start to stop
DOWN Run sweep from stop to start
Query :DIRection? Query direction of sweep
Description Normally, a sweep is run from the start level to the stop level. The :STARt and
:STOP, or :CENTer and :SPAN commands are used to set these levels.
This command lets you change the execution direction of the sweep. With DOWN
selected, the sweep will begin at the stop level and end at the start level. Selecting
UP restores sweep operation to the normal start to stop direction.
Configure list
VOLTage <NRf list>
:SOURce[1]:LIST:VOLTage <NRf list>Define source 1 list
:SOURce2:LIST:VOLTage <NRf list>Define source 2 list
Parameters <NRf list> = NRf, NRf … NRf
NRf =
-30 to 30 Source value (volts)
Query :VOLTage? Query source list
Description These commands are used to define a list of source values (up to 100) for the list
sourcing mode of operation. When operation is started, the instrument will
sequentially source each voltage value in the list. A current measurement is
performed at each source level.
The following command shows the proper format for defining a list using source
values of 10 V, 13 V, and 5 V:
:SOURce[1]:LIST:VOLTage 10, 13, 5
If using manual source ranging, you can use autorange for source values that are
not within a single range.
NOTE In order to execute a source list, the selected source must be in the list sourcing mode,
and the product of the arm and trigger count should be at least the same as the number
of source points in the list.
Use the VOLTage:MODE command to select the LIST sourcing mode. See
“Select sourcing mode,” page Section 16-40. The trigger count is set using the
TRIGger:COUNt command. See “Trigger subsystem,” page Section 16-58.
APPend <NRf list>
:SOURce[1]:LIST:VOLTage:APPend <NRf list>Add value(s) to source 1 list
:SOURce2:LIST:VOLTage:APPend <NRf list>Add value(s) to source 2 list
Parameters <NRf list> = NRf, NRf … NRf
NRf =
-30 to 30 Source value (volts)
Description These commands are used to add one or more values (up to 100) to a source list
that already exists. The source values are appended to the end of the list. By
using multiple appended lists, up to 3000 points can be in a list.
