[SOURce[1|2]]:VOLTage:UNIT
This command sets or queries the units of output amplitude for the specified
channel. This command does not affect the offset, High level, or Low level of
output. The setting of this command is not affected by the units setting of
[SOURce[1|2]]:VOLTage[:LEVel][:IMMediate][:AMPLitude] command.
If your instrument is a dual-channel model and the
[SOURce[1|2]]:VOLTage:CONCurrent[:STATe] command is set to ON, then the
units of the other channel are set the same.
