Specifications
LIST SUBSYSTEM
This subsystem controls the generation of parameter lists that sequence the power supply output through
values of voltage and current. Two subsystem commands specify lists of output voltages (LIST:VOLT),
and currents (LIST:CURR), the time interval that each value (point) of a list is to remain in effect
(LIST:VOLT:TIME and LIST:CURR:TIME), and the list step(LIST:VOLT:STEP and
LIST:CURR:STEP). A count command (LIST:COUN) determines how many times the power supply
sequences through a list before that list is completed. Each list can have from 1 to 20 points.
LIST:COUN
This command sets the number of times that the list is executed before it is completed. The command
accepts parameters in the range 1 through 60000, but any number greater than 65534.

LIST:CURR; LIST:VOLT
LIST:CURR
This command specifies the output current points in a list. The current points are given in the command
parameters, which are separated by commas. Up to 20 points may be entered and the output current values
specified by the points will be generated in the same order as they were entered.
