use this amplitude; otherwise, the instrument would display a prompt message and set the amplitude
to the amplitude upper limit of the new configuration automatically.
 You can also use "High Level" or "Low Level" to set the amplitude and offset.
Amplitude = High Level - Low Level
Offset = (High Level + Low Level)/2
Return Format
The query returns the waveform amplitude in scientific notation, with 7 effective digits. For example,
5.000000E+00 (the waveform amplitude is 5 Vpp).
Example
:SOUR1:VOLT 5 /*Sets the waveform amplitude of CH1 to 5 Vpp.*/
:SOUR1:VOLT? /*Queries the waveform amplitude of CH1 and the query returns 5.000000E+00.*/
[:SOURce[<n>]]:VOLTage[:LEVel][:IMMediate]:HIGH
Syntax
[:SOURce[<n>]]:VOLTage[:LEVel][:IMMediate]:HIGH {<voltage>|MINimum|MAXimum}
[:SOURce[<n>]]:VOLTage[:LEVel][:IMMediate]:HIGH? [MINimum|MAXimum]
Description
Sets the high level value of the waveform of the specified channel.
Queries the high level value of the waveform of the specified channel.

Remarks
 When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
 You can also use the "Amplitude" (
[:SOURce[<n>]]:VOLTage[:LEVel][:IMMediate][:AMPLitude]) and
"Offset" (
[:SOURce[<n>]]:VOLTage[:LEVel][:IMMediate]:OFFSet) to set the high level and low level.
High Level = Offset + Amplitude/2
Low Level = Offset - Amplitude/2
Return Format
The query returns the waveform high level value in scientific notation, with 7 effective digits. For example,
3.500000E+00 (the waveform high level value is 3.5 Vpp).
Example
:SOUR1:VOLT:HIGH 3.5 /*Sets the high level value of the waveform of CH1 to 3.5 Vpp.*/
:SOUR1:VOLT:HIGH? /*Queries the high level value of the waveform of CH1 and the query returns
3.500000E+00.*/
[:SOURce[<n>]]:VOLTage[:LEVel][:IMMediate]:LOW
Syntax
[:SOURce[<n>]]:VOLTage[:LEVel][:IMMediate]:LOW {<voltage>|MINimum|MAXimum}
[:SOURce[<n>]]:VOLTage[:LEVel][:IMMediate]:LOW? [MINimum|MAXimum]
Description
Sets the low level value of the waveform of the specified channel.
Queries the low level value of the waveform of the specified channel.
