Details
This command defines a list of up to 99 values for a specified list. Creating a list with more than 99
step points results in error 201,"Too many list points."
When you specify the values for a list, you should keep the value order in the string identical with the
sequence that the list executes.
To add source values to an existing list, use the following command:
[:SOURce[n]]:LIST<listNumber>:<element>:APPend
All of the values specified by this command are temporary until they are saved by sending the
[:SOURce[n]]:LIST:SAVE:INTernal
command.
To create a valid list, the number of points for voltage, current, and dwell must be the same. If they
are not the same, when you save the list by sending the
[:SOURce[n]]:LIST:SAVE:INTernal
command, the instrument will generate error 202, "List lengths not equivalent."
