Frequency Coupling
1.
To Enable Frequency Coupling Function
Press
[FreqCoup]
to turn frequency coupling On or Off. The default is Off.
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: FreqCH2/FreqCH1=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: AmplCH2-AmplCH1=AmplDev.
Ratio:
the amplitude ratio of CH1 and CH2. The resulting signal is represented by: AmplCH2/AmplCH1=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: PhaseCH2-PhaseCH1=PhaseDev.
Ratio:
the phase ratio of CH1 and CH2. The resulting signal is represented by: PhaseCH2/PhaseCH1=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 is changed, the phase of the other channel will be
changed accordingly. At this point, aligning phase between the two channels can be achieved without executing the
Eqphase
operation.
3.
Channel coupling and channel function are mutually exclusive. When channel coupling is enabled, the menu
Channel Copy
is
hidden.
