Usage

Details
This command defines a list of up to 100 source values for a source list. This list is used by the
:SOURce[1]:SWEep:<function>:LIST command to define the source values for the sweep.
When you start the sweep, the instrument sequentially sources each current or voltage value in the list. A
measurement is performed at each source level.
If there is an existing list, it is replaced by the new list.
When you send this command, the instrument creates a source configuration list named
CurrCustomSweepList if the function is set to current or VoltCustomSweepList if the function is set to
voltage.
To add source values to an existing list, use the :SOURce[1]:LIST:<function>:APPend command.
Example
*RST
