LIST Subsystem

List commands program an output sequence of multiple voltage or current settings. A comma-

delimited list of up to 512 steps may be programmed. Note that these commands only apply in the

presently active priority mode, either voltage priority or current priority.

[SOURce:]LIST:COUNt <value>|MIN|MAX|INFinity

[SOURce:]LIST:COUNt? [MIN|MAX]

Sets the list repeat count. This sets the number of times that a list is executed before it completes. The

count range is 1 through 4096. Infinity runs the list continuously.

Parameter Typical Return

1 – 4096, *RST 1 <count>

Sets the list count to 10: LIST:COUN10

[SOURce:]LIST:CURRent[:LEVel] <value>{,<value>}

[SOURce:]LIST:CURRent[:LEVel]?

[SOURce:]LIST:VOLTage[:LEVel] <value>,{<value

[SOURce:]LIST:VOLTage[:LEVel]?

Specifies the setting for each list step. Values are specified in either amperes or volts.

Parameter Typical Return

Voltage: 0 to 102% of rating

Current: -102% to 102% of rating

Programs a current list. The list contains 3 steps:LIST:CURR 3,2,1

Programs a voltage list. The list contains 3 steps:LIST:VOLT20,10,5

[SOURce:]LIST:DWELl <value>{,<value>}

[SOURce:]LIST:DWELl?

Specifies the dwell time for each list step. Dwell time is the time that the output will remain at a

specific step. Dwell times can be programmed from 0 through 262.144 seconds with the following

resolution:

Range in seconds Resolution

0 - 0.262144 1 microsecond

0.262144 - 2.62144 10 microseconds

2.62144 - 26.2144 100 microseconds

26.2144 - 262.144 1 millisecond
