[:SOURce[<n>]]:FREQuency:COUPle:RATio
Syntax [:SOURce[<n>]]:FREQuency:COUPle:RATio <ratio>
[:SOURce[<n>]]:FREQuency:COUPle:RATio?
Description Set the frequency ratio in the frequency coupling.
Query the frequency ratio in the frequency coupling.
Parameter Name Type Range Default
[<n>] Discrete 1|2 1
<ratio> Real 0.000 001 to 1 000 000 1
Explanation  Please select the desired frequency coupling mode
( [:SOURce[<n>]]:FREQuency:COUPle:MODE ) and set the corresponding
frequency deviation ( [:SOURce[<n>]]:FREQuency:COUPle:OFFSet ) or
frequency ration before enabling the frequency coupling function
( [:SOURce[<n>]]:FREQuency:COUPle[:STATe] ). You cannot set the frequency
coupling mode and the frequency deviation/ratio after the frequency coupling
function is enabled.
 When the frequency coupling function is disabled, sending this command can set
the frequency ratio if the current frequency coupling mode is frequency ratio;
sending this command can select the frequency ratio coupling mode and set the
frequency ratio if the current frequency coupling mode is frequency deviation.
 You can also send the :COUPling:FREQuency:RATio command to set and query
the frequency ratio in the frequency coupling of the specified channel.
Return Format The query returns the frequency ratio in scientific notation with 7 effective digits, for
example, 1.001230E+02 (the frequency ratio in the frequency coupling is 100.123).
Example :FREQ:COUP:RAT 100.123 /*Set the frequency ratio in the frequency coupling to
100.123*/
:FREQ:COUP:RAT? /*Query the frequency ratio in the frequency coupling
and the query returns 1.001230E+02*/
