[:SOURce[]]:FREQuency:COUPle[:STATe]
Syntax [:SOURce[]]:FREQuency:COUPle[:STATe] {ON|1|OFF|0}
[:SOURce[]]:FREQuency:COUPle[:STATe]?
Description Turn on or off the frequency coupling function.
Query the on/off status the frequency coupling function.
Parameter Name Type Range Default
[] Discrete 1|2 1
{ON|1|OFF|0} Bool ON|1|OFF|0 OFF
Explanation  When the frequency coupling function is turned off, you can select the frequency
coupling mode and set the corresponding frequency deviation or ratio. After the
frequency coupling function is turned on, CH1 and CH2 are the reference source
of each other; when the frequency of one channel (this channel is the reference
source) is changed, the frequency of the other channel will be adjusted
automatically and the channel will always keep the specified frequency deviation
or ratio with the reference channel.
 Please select the desired frequency coupling mode
( [:SOURce[]]:FREQuency:COUPle:MODE ) and set the corresponding
frequency deviation ( [:SOURce[]]:FREQuency:COUPle:OFFSet ) or frequency
ration ( [:SOURce[]]:FREQuency:COUPle:RATio ) before enabling the
frequency coupling function. You cannot set the frequency coupling mode and
the frequency deviation/ratio after the frequency coupling function is enabled.
 You can also send the :COUPling:FREQuency[:STATe] command to set or query
the status of the frequency coupling function.
Return Format The query returns ON or OFF.
Example :FREQ:COUP ON /*Turn on the frequency coupling function */
:FREQ:COUP? /*Query the on/off status the frequency coupling function and
the query returns ON*/
