the coupling base respectively as shown in the figure below, indicating that the
generator is in frequency, phase and amplitude couplings. Change the frequency,
phase and amplitude of CH2 to 100Hz, 0° and 1Vpp respectively and the
parameters of CH1 will change to 200Hz, 10° and 2Vpp automatically.
Figure 10-4 Channel Coupling
Key Points:
Channel coupling is only available when the waveforms of the two channels
are basic waveforms, including Sine, Square, Ramp and Arbitrary waveform
(except DC).
If the sum of the frequency, phase or amplitude of the base channel and the
corresponding deviation set exceeds the upper limit of frequency, phase or
amplitude of the non-base channel, the generator will adjust the frequency,
phase or amplitude of the non-base channel to avoid parameter overrange.
The frequency, phase and amplitude of the non-base channel cannot be
modified directly.
When the phase of the base channel is changed, the phase (phase displayed
on the interface) of the non-base channel will change accordingly. At this point,
align phase between the two channels can be realized without executing the
Align Phase operation.
