Remarks
 When [<n>] is omitted, the commands set and query the related parameters of CH1 by default.
 Select the desired frequency coupling mode and set the corresponding frequency deviation or
frequency ratio when the frequency coupling function is disabled. After the frequency coupling
function is enabled, CH1 and CH2 take each other as the reference source. When the frequency of one
channel (this channel is taken as the reference source) is modified, the frequency of the other channel
is automatically modified accordingly and always keeps the specified frequency deviation or ratio with
that of the reference channel.
 Select the desired frequency coupling mode (
:COUPling[<n>]:FREQuency:MODE) and set the
corresponding frequency deviation (
:COUPling[<n>]:FREQuency:DEViation) or frequency ratio
(
:COUPling[<n>]:FREQuency:RATio) before enabling the frequency coupling function. You cannot set
the frequency coupling mode and frequency deviation/ratio after the frequency coupling function is
enabled.
 You can also send the
[:SOURce[<n>]]:FREQuency:COUPle[:STATe] command to set and query the
on/off status of the frequency coupling function.
Return Format
The query returns ON or OFF.
Example
:COUP1:FREQ ON /*Enables the frequency coupling function of CH1.*/
:COUP1:FREQ? /*Queries the on/off status of the frequency coupling function of CH1 and the query
returns ON.*/
:COUPling[<n>]:PHASe:DEViation
Syntax
:COUPling[<n>]:PHASe:DEViation <deviation>
:COUPling[<n>]:PHASe:DEViation?
Description
Sets the phase deviation in the phase coupling of the specified channel.
Queries the phase deviation in the phase coupling of the specified channel.

Remarks
 When [<n>] is omitted, the commands set and query the related parameters of CH1 by default.
 Select the desired phase coupling mode (
:COUPling[<n>]:PHASe:MODE) and set the corresponding
phase deviation or phase ratio (
:COUPling[<n>]:PHASe:RATio) before enabling the phase coupling
function (
:COUPling[<n>]:PHASe[:STATe]). You cannot set the phase coupling mode and phase
deviation/ratio after the phase coupling function is enabled.
 When the phase coupling function is disabled, if the current phase coupling mode is phase deviation,
sending this command can set the phase deviation; if the current phase coupling mode is phase ratio,
sending this command can set the phase coupling mode to phase deviation and set the phase
deviation.
