:COUPling[:STATe]
Syntax
:COUPling[:STATe] {ON|1|OFF|0}
:COUPling[:STATe]?
Description
Enable or disable the frequency coupling, phase coupling and amplitude coupling of
the channel at the same time.
Query the on/off states of the frequency coupling, phase coupling and amplitude
coupling of the channel.

Explanation
DG1000Z supports the frequency, amplitude and phase coupling functions. After
the coupling functions are enabled, CH1 and CH2 take each other as the
reference source. When the frequency, amplitude or phase of a channel (this
channel is the reference source) is changed, the frequency, amplitude or phase
of the other channel changes accordingly automatically and always keeps the
specified frequency deviation/ratio, amplitude deviation/ratio or phase
deviation/ratio with that of the reference channel.
You can also enable or disable the frequency coupling function
), phase coupling function
) and amplitude coupling function
) respectively.
Return Format
The query returns a string consisting of 3 parts (represent the on/off states of the
frequency coupling, phase coupling and amplitude coupling functions in order)
separated by commas, for example, FREQ:ON,PHASE:OFF,AMPL:OFF.
Example
:COUP ON /*Enable the frequency coupling, phase coupling and amplitude
coupling of the channel at the same time*/
:COUP? /*Query the on/off states of the frequency coupling, phase coupling
and amplitude coupling of the channel and the query returns
FREQ:ON,PHASE:ON,AMPL:ON*/
