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 10-5 Channel Coupling
Key Points:
z Channel coupling is only available when the waveforms of the two channels
are basic waveforms, including Sine, Square, Ramp and Arbitrary waveform
(except DC).
z 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.
z The frequency, phase and amplitude of the non-base channel can not be
modified directly.
z 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.
