[:SOURce[<n>]]:VOLTage[:LEVel][:IMMediate][:AMPLitude]
Syntax [:SOURce[<n>]]:VOLTage[:LEVel][:IMMediate][:AMPLitude]
{<amplitude>|MINimum|MAXimum}
[:SOURce[<n>]]:VOLTage[:LEVel][:IMMediate][:AMPLitude]? [MINimum|MAXimum]
Description Set the waveform amplitude of the specified channel (basic waveforms and arbitrary
waveform).
Query the waveform amplitude of the specified channel (basic waveforms and
arbitrary waveform).
Parameter
Name Type Range Default
[<n>] Discrete 1|2 1
<amplitude> Real Refer to the “Explanation” 5Vpp
Explanation  When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related
parameters of CH1 by default.
 The minimum of <amplitude> is 2mVpp and the maximum is limited by the
“Impedance” (
:OUTPut[<n>]:IMPedance or :OUTPut[<n>]:LOAD) and
“Frequency/Period” (
[:SOURce[<n>]]:FREQuency[:FIXed] or
[:SOURce[<n>]]:PERiod[:FIXed]) settings. If the amplitude in the command is
greater than the corresponding upper limit or lower than the corresponding
lower limit, the system will set the waveform amplitude of the specified channel
to the amplitude upper limit or lower limit.
 The current amplitude of the instrument is the default value or the amplitude set
formerly. When the configuration (such as the frequency) of the instrument is
changed, the instrument still uses the current amplitude if the amplitude is valid;
the instrument displays prompt message and set the amplitude to the amplitude
upper limit of the new configuration automatically if the current amplitude is
invalid.
 You can use the “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 5Vpp).
Example :SOUR1:VOLT 5 /*Set the waveform amplitude of CH1 to 5Vpp*/
:SOUR1:VOLT? /*Query the waveform amplitude of CH1 and the query returns
5.000000E+00*/
