2. To Enable Coupling Function
Press Ampl Cpl to turn amplitude coupling “On” or “Off”. The default is “Off”.
Phase Coupling
1. Phase Coupling Mode
Press PCpl Mode to select “PhaseDev” or “Ratio” and then input the desired
value using the numeric keyboard.
 PhaseDev: the phase deviation between CH1 and CH2. The parameter
relations are as shown below:

 Ratio: the phase ratio of CH1 and CH2. The parameter relations are as
shown below:

Note: please set this parameter before enable the phase coupling function.
When phase coupling is enabled, this menu is grayed out and disabled and you
can not set the phase deviation or phase ratio.
2. To Enable Coupling Function
Press PhaseCpl to turn phase coupling “On” or “Off”. The default is “Off”.
When the corresponding coupling functions are enabled, green “*” marks are
separately displayed on the left of the frequency, amplitude and phase of the two
channels as shown in the figure below, indicating that the generator is in frequency,
phase and amplitude couplings at the same time. For example, when the frequency,
amplitude and phase deviation are set to “100Hz”, “1Vpp” and “10°” respectively,
change the frequency, amplitude and phase of CH1 to 200Hz, 2Vpp and 20°
respectively and the parameters of CH2 will be changed to 300Hz, 3Vpp and 30°
automatically; use CH1|CH2 to switch to CH2, change the frequency, amplitude
and phase of CH2 to 200Hz, 2Vpp and 20° respectively and the parameters of CH1
will be changed to 100Hz, 1Vpp and 10° automatically.
