2. To Select Frequency Coupling Mode
Press FreqMode to choose ―Deviation‖ or ―Ratio‖, and then use the numeric
keyboard or knob and arrow keys to input the desired value.
 Deviation: the frequency deviation between CH1 and CH2. The resulting
signal is represented by: FreqCH2-FreqCH1=FreqDev.
 Ratio: the frequency ratio of CH1 and CH2. The resulting signal is
represented by: Freq
CH2
/Freq
CH1
=FreqRatio.
Amplitude Coupling
1. To Enable Amplitude Coupling Function
Press AmplCoup to turn amplitude coupling ―On‖ or ―Off‖. The default is ―Off‖.
2. To Select Amplitude Coupling Mode
Press AmplMode to choose ―Deviation‖ or ―Ratio‖, and then use the numeric
keyboard or knob and arrow keys to input the desired value.
 Deviation: the amplitude deviation between CH1 and CH2. The resulting
signal is represented by: Ampl
CH2
-Ampl
CH1
=AmplDev.
 Ratio: the amplitude ratio of CH1 and CH2. The resulting signal is
represented by: Ampl

=AmplRatio.
Phase Coupling
1. To Enable Phase Coupling Function
Press PhaseCoup to turn phase coupling ―On‖ or ―Off‖. The default is ―Off‖.
2. To Select Phase Coupling Mode
Press PhaseMode to choose ―Deviation‖ or ―Ratio‖, and then use the numeric
keyboard or knob and arrow keys to input the desired value.
 Deviation: the phase deviation between CH1 and CH2. The resulting
signal is represented by: Phase
CH2
-Phase
CH1
=PhaseDev.
 Ratio: the phase ratio of CH1 and CH2. The resulting signal is represented
by: Phase

=PhaseRatio.
Key Points:
1. Channel coupling is only available when both the waveforms of the two
channels are basic waveforms including Sine, Square, Ramp and Arbitrary.
2. When the Phase Coupling function is enabled, if the phase of one channel
