3 Language Dictionary134 Keysight Models 6811C, 6812C, and 6813C Programming GuideSource Subsystem (List) CommandsThis subsystem controls the generation of complex sequences of output changeswith rapid, precise timing and synchronized with internal or external signals. Eachsubsystem command for which lists can be generated has an associated list ofvalues that specify the output at each list step. LIST:COUNt determines how manytimes the sequences through a list before that list is completed. LIST:DWELlspecifies 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 orto sequence through all of its points.All active subsystems that have their modes set to LIST must have the samenumber of points (up to 100), or an error is generated when the first list point istriggered. The only exception is a list consisting of only one point. Such a list istreated as if it had the same number of points as the other lists, with all of theimplied points having the same value as the one specified point. All list point datais stored in non-volatile memory.Subsystem syntaxNOTE MODE commands such as VOLTage:MODE LIST are used to activate lists forspecific functions. However, the LIST:DWELl command is active whenever anyfunction is set to list mode. Therefore, LIST:DWELl must always be set either toone point, or to the same number of points as the active list.[SOURce:]LIST:COUNt | INFinity Sets the list repeat count:CURRent {, } Sets the peak current limit list:POINts?
