[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
10
(P / 0.001), where P = Vrms
2
/ R
