1. Click or tap the Freq Cpl on/off switch to enable or disable the frequency coupling.
The default setting is "Off".
2. Click or tap the Freq Cpl drop-down button to select "Offset" or "Ratio". Then click
or tap the input field to set the deviation or ratio value.
- Offset: the frequency deviation between CH1 and CH2. Set the frequency of
base channel to F
the other channel is F = F
- Ratio: the frequency ratio of CH1 and CH2. Set the frequency of base channel to
F
basic
F = F
Phase Coupling
Phase coupling allows you to couple phases between channels, either by a constant
deviation or ratio between them.
1. Click or tap the Phase Cpl on/off switch to enable or disable the phase coupling.
The default setting is "Off".
2. Click or tap the Phase Cpl drop-down button to select "Offset" or "Ratio". Then
click or tap the input field to set the deviation or ratio value.
- Offset: the phase deviation between CH1 and CH2. Set the phase of base
channel to P
channel is P = P
- Ratio: the phase ratio of CH1 and CH2. Set the phase of base channel to P
and the phase ratio to P
P
basic
Amplitude Coupling
Amplitude coupling allows you to couple amplitudes between channels, either by a
constant deviation or ratio between them.
1. Click or tap the Ampl Cpl on/off switch to enable or disable the amplitude
coupling. The default setting is "Off".
2. Click or tap the Ampl Cpl drop-down button to select "Offset" or "Ratio". Then
click or tap the input field to set the deviation or ratio value.
- Offset: the amplitude deviation between CH1 and CH2. Set the amplitude of
base channel to A
of the other channel is A = A
- Ratio: the amplitude ratio of CH1 and CH2. Set the amplitude of base channel
to A
channel is A = A
