:COUPling:AMPL[:STATe]
Syntax :COUPling:AMPL[:STATe] {ON|1|OFF|0}
:COUPling:AMPL[:STATe]?
Description Enable or disable the amplitude coupling function.
Query the on/off status of the amplitude coupling function.
Parameter Name Type Range Default
{ON|1|OFF|0} Bool ON|1|OFF|0 OFF
Explanation  After the amplitude coupling function is enabled, CH1 and CH2 take each other as
the reference source. When the amplitude of a channel (this channel is the
reference source) is changed, the amplitude of the other channel changes
accordingly automatically and always keeps the specified amplitude deviation or
ratio with that of the reference channel.
 Select the desired amplitude coupling mode ( :COUPling:AMPL:MODE ) and set the
corresponding amplitude deviation ( :COUPling:AMPL:DEViation ) or amplitude
ratio ( :COUPling: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[]]:VOLTage:COUPle[:STATe] command to
set or query the on/off status of the amplitude coupling function.
Return Format The query returns ON or OFF.
Example :COUP:AMPL ON /*Enable the amplitude coupling function*/
:COUP:AMPL? /*Query the on/off status of the amplitude coupling function and
the query returns ON*/
