Configure list
:CURRent <NRf list>
:VOLTage <NRf list>
:SOURce[1]:LIST:CURRent <NRf list> Define I-Source list
:SOURce[1]:LIST:VOLTage <NRf list> Define V-Source list
Parameters <NRf list> = NRf, NRf … NRf
NRf = -105e-3 to 105e-3 I-Source value
-210 to 210 V-Source value
Query :CURRent? Query I-Source list
:VOLTage? Query V-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 current or voltage value in the list. A measure-
ment is performed at each source level.
The following command shows the proper format for defining an I-Source
list using current source values of 10mA, 130mA, and 5mA:
:SOURce[1]:LIST:CURRent 0.01, 0.13, 0.005
If using manual source ranging, you can use auto range 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 :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 LIST sourcing mode. See Select
sourcing mode. The trigger count is set using the TRIGger:COUNt
command. See Trigger subsystem.
:APPend <NRf list>
:SOURce[1]:LIST:CURRent:APPend <NRf list> Add value(s) to I-Source list
:SOURce[1]:LIST:VOLTage:APPend <NRf list> Add value(s) to V-Source list
Parameters <NRf list> = NRf, NRf … NRf
NRf = -105e-3 to 105e-3 I-Source value
-210 to 210 V-Source value
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.)
