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
<list value 1>,<list value 2>,<list value 3>
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
