Description
Command
Sets the saved voltage data items to the numerical value 0
– 255.
Query
Returns the saved voltage data items as numerical values.
Example
Command
:DATA:ITEM:U 1,1,1,1,0,0,0
Set the voltage RMSdata of Channels 1
– 4 to ON.
Query
:DATA:ITEM:U?
Response
:DATAOUT:ITEM:U 1,1,1,1,0,0,0 (WHEN HEADER IS ON)
1,1,1,1,0,0,0 (WHEN HEADER IS OFF)
Note
Data in the THD/RF items changes according to the integration mode setting.
Some items are unselectable due to the wiring and integration mode.
When an unselectable item is specified, an execution error will occur and other items will also
not be set.
Use this command after :DATAout:ITEM:NORMal and :DATAout:ITEM:SUMCommand.
