Return Format
The query returns OFFS or RAT.
Example
:FREQ:COUP:MODE OFFS /*Sets the frequency coupling mode of CH1 to Frequency Deviation.*/
:FREQ:COUP:MODE? /*Queries the frequency coupling mode and the query returns OFFS.*/
[:SOURce[<n>]]:FREQuency:COUPle:OFFSet
Syntax
[:SOURce[<n>]]:FREQuency:COUPle:OFFSet <frequency>
[:SOURce[<n>]]:FREQuency:COUPle:OFFSet?
Description
Sets the frequency deviation in the frequency coupling.
Queries the frequency deviation in the frequency coupling.

Remarks
Select the desired frequency coupling mode (
[:SOURce[<n>]]:FREQuency:COUPle:MODE
) and set the
corresponding frequency deviation or frequency ratio (
[:SOURce[<n>]]:FREQuency:COUPle:RATio
before enabling the frequency coupling function (
[:SOURce[<n>]]:FREQuency:COUPle[: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
deviation, sending this command can set the frequency deviation; if the current frequency coupling
mode is frequency ratio, sending this command can set the frequency coupling mode to frequency
deviation and set the frequency deviation.
:COUPling[<n>]:FREQuency:DEViation
frequency deviation in the frequency coupling of the specified channel.
Return Format
The query returns the frequency deviation in scientific notation, with 7 effective digits. For example,
1.02 (the frequency deviation in the frequency coupling is 100 Hz).
Example
:FREQ:COUP:OFFS 100 /*Sets the frequency deviation in the frequency coupling to 100 Hz.*/
:COUP1:FREQ:DEV? /*Queries the frequency deviation in the frequency coupling and the query
returns 1.02.*/
[:SOURce[<n>]]:FREQuency:COUPle:RATio
Syntax
[:SOURce[<n>]]:FREQuency:COUPle:RATio <ratio>
[:SOURce[<n>]]:FREQuency:COUPle:RATio?
Description
Sets the frequency ratio in the frequency coupling.
Queries the frequency ratio in the frequency coupling.
