Source Subsystem (List) Commands

This subsystem controls the generation of complex sequences of output changes

with rapid, precise timing and synchronized with internal or external signals. Each

subsystem command for which lists can be generated has an associated list of

values that specify the output at each list step. LIST:COUNt determines how many

times the sequences through a list before that list is completed. LIST:DWELl

specifies the time interval that each value (point) of a list is to remain in effect.

LIST:STEP determines if a trigger causes a list to advance only to its next point or

to sequence through all of its points.

All active subsystems that have their modes set to LIST must have the same

number of points (up to 100), or an error is generated when the first list point is

triggered. The only exception is a list consisting of only one point. Such a list is

treated as if it had the same number of points as the other lists, with all of the

implied points having the same value as the one specified point. All list point data

is stored in non-volatile memory.

Subsystem syntax

NOTE

MODE commands such as VOLTage:MODE LIST are used to activate lists for

specific functions. However, the LIST:DWELl command is active whenever any

function is set to list mode. Therefore, LIST:DWELl must always be set either to

one point, or to the same number of points as the active list.
