Syntax and Commands

3-88 AFG3000 Series Arbitrary/Function Generators Reference Manual

[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.
