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

{ON|1|OFF|0}
Bool
ON|1|OFF|0
OFF
Remarks
 When [<n>] is omitted, the commands set and query the related parameters of CH1 by default.
 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.
 Select the desired amplitude coupling mode (
:COUPling[<n>]:AMPL:MODE) and set the corresponding
amplitude deviation (
:COUPling[<n>]:AMPL:DEViation) or amplitude
ratio(
:COUPling[<n>]:AMPL:RATio) before enabling the amplitude coupling function. You cannot set
the amplitude coupling mode and amplitude deviation/ratio after the amplitude coupling function is
enabled.
 You can also send the
[:SOURce[<n>]]:VOLTage:COUPle[:STATe] command to set and query the
on/off status of the amplitude coupling function.
Return Format
The query returns ON or OFF.
Example
:COUP1:AMPL ON /*Enables the amplitude coupling function of CH1.*/
:COUP1:AMPL? /*Queries the on/off status of the amplitude coupling function and the query returns ON.*/
:COUPling[<n>]:FREQuency:DEViation
Syntax

:COUPling[<n>]:FREQuency:DEViation?
Description

 Select the desired frequency coupling mode (
