:COUPling:AMPL:RATio
Syntax :COUPling:AMPL:RATio {|MINimum|MAXimum}
:COUPling:AMPL:RATio?
Description Set the amplitude ratio in the amplitude coupling.
Query the amplitude ratio in the amplitude coupling.
Parameter Name Type Range Default
Real 0.001 to 1000 1
Explanation  Select the desired amplitude coupling mode ( :COUPling:AMPL:MODE ) and set
the corresponding amplitude deviation ( :COUPling:AMPL:DEViation ) or
amplitude ratio before enabling the amplitude coupling function
( :COUPling:AMPL[:STATe] ). You cannot set the amplitude coupling mode and
amplitude deviation/ratio after the amplitude coupling function is enabled.
 When the amplitude coupling function is disabled, if the current amplitude
coupling mode is amplitude ratio, send this command can set the amplitude
ratio; if the current amplitude coupling mode is amplitude deviation, send this
command can set the amplitude coupling mode to amplitude ratio and set the
amplitude ratio.
Return Format The query returns the amplitude ratio in scientific notation. The return value contains
7 effective digits, for example, 1.123000E+00 (the amplitude ratio is 1.123).
Example :COUP:AMPL:RAT 1.123 /*Set the amplitude ratio in the amplitude coupling to
1.123*/
:COUP:AMPL:RAT? /*Query the amplitude ratio in the amplitude coupling
and the query returns 1.123000E+00*/
