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