Output Configuration Commands 4

U2761A Programmer’s Reference 45

[SOURce:]VOLTage[:LEVel][:IMMediate][:AMPLitude]

Syntax

[SOURce:]VOLTage[:LEVel][:IMMediate][:AMPLitude]

<amplitude> [VPP|VRMS|DBM]

This command sets the output amplitude with optional unit.

[SOURce:]VOLTage[:LEVel][:IMMediate][:AMPLitude]?

This query returns the output amplitude for the currently selected

function and unit. Values are always returned in the units set by the most

recent [SOURce:]VOLTage[:LEVel][:IMMediate]:UNIT command.

Parameter

Remarks

The RMS and dBm values can be computed as follows:

Vrms = Vpeak / Crest factor

dBm = 10 × log

(P / 0.001), where P = Vrms

/ R
