[:SOURce[<n>]]:VOLTage:COUPle[:STATe] 
Syntax 
[:SOURce[<n>]]:VOLTage:COUPle[:STATe] {ON|1|OFF|0} 
[:SOURce[<n>]]:VOLTage:COUPle[:STATe]? 
Description 
Enables or disables the amplitude coupling function. 
Queries the on/off status of the amplitude coupling function.

{ON|1|OFF|0} 
Bool 
ON|1|OFF|0 
OFF 
Remarks 
  After the amplitude coupling function is enabled, CH1 and CH2 take each other as the reference source. 
When the amplitude of one channel (this channel is taken as the reference source) is modified, the 
amplitude of the other channel is automatically modified accordingly and always keeps the specified 
amplitude deviation or ratio with that of the reference channel. 
  You can also send the 
:COUPling[<n>]:AMPL[:STATe] command to set and query the on/off status of 
the amplitude coupling function. 
Return Format 
The query returns ON or OFF. 
Example   
:SOUR1:VOLT:COUP ON /*Enables the amplitude coupling function.*/ 
:SOUR1:VOLT:COUP?      /*Queries the on/off status of the amplitude coupling function and the query 
returns ON.*/ 
[: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 
Sets the waveform amplitude of the specified channel. 
Queries the waveform amplitude of the specified channel.

Remarks   
  When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default. 
  The minimum of <amplitude> is 2 mVpp 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 
value in the command is greater than the corresponding amplitude upper limit or smaller than the 
corresponding amplitude lower limit, the waveform amplitude of the specified channel will be set to 
the amplitude upper limit or lower limit. 
  The current amplitude of the instrument is the default value or the one previously set. When the 
instrument configuration (e.g. frequency) is changed, if this amplitude is valid, the instrument will still
