SCPI Command Reference
18-93
Description
This command is 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 2500 points can be in a list.)
POINts?
:SOURce[1]:LIST:CURRent:POINts?
Query length of I-Source list
:SOURce[1]:LIST:VOLTage:POINts?
Query length of V-Source list
Description
This command is used to determine the length of the specified source list.
The response message indicates the number of source values in the list.
STARt <n>
:SOURce[1]:LIST:CURRent:STARt <n>
Set current list start point
:SOURce[1]:LIST:VOLTaget:STARt <n>
Set voltage list start point
Parameters
<n> =
1 to 100
Set start point of list sweep
MINimum
1
MAXimum
100
DEFault
1
Description
These commands set the starting point in the current or voltage list
sweep. The <n> parameter is 1-based, and it must be less than or equal
to the number of points in the sweep. The new starting location will
only be used when the direction of the sweep is up
(:SOUR:LIST:CURR:DIR UP, for example). Changing the direction to
down will make the sweep start at the last point in the list, but the start-
ing point will be restored when the direction is changed to up. If the
sweep reaches the end of the list, the sweep will continue from the first
point in the list. The starting points for voltage and current sweeps are
saved separately, and are part of a user-saved setup.
Configure memory sweep
A memory sweep lets you perform a sweep using setups stored in up to 100 memory loca-
tions. This allows you to sweep using multiple source-measure operations and math
expressions. (See
“CALCulate[1],” page 18-24
, subsystem.)
NOTE
In order to run a memory sweep, the memory function must be selected, and the
trigger count must be the same as the number of memory points in the sweep.
Use the :FUNCtion:MODE command to select the MEMory function. (See
“Select function modes,” page 18-73
.) Arm count (ARM:COUNt) and trigger
count (TRIGger:COUNt) are set from the Trigger Subsystem.
When memory is initialized (:SYSTem:MEMory:INITialize), all 100 memory
locations for a memory sweep are initialized to the present setup configuration
