5.13 Dual Channel Operations
You enter the dual channel configuration menu by pressing 【Dual Channel】key.
5.13.1 Operation Mode
There are two modes for dual channel operation: parameters coupling and waveform combine. While,
parameters coupling includes frequency coupling and amplitude coupling. Using parameter coupling
way can generate two synchronous changing signal, take difference signal or multiplier signal for
example. Using the waveform combine way can add harmonic, noise or pulse on output waveforms
to realize a analog signal.
If enable the parameters coupling or waveform combine, only CHB enter into dual channel
operations. Otherwise, the two channels are still independent one.
5.13.2 Frequency Coupling
Frequency coupling allows you to couple frequencies between the two channels. Channel
frequencies can be linked with a constant ratio or difference between them.
Press the 〖Freq Cpl On/Off〗 softkey to turn frequency coupling on or off. Once configure CHA
frequency, the frequency value of CHB can be changed automatically. Well noted that the CHB can't
be set.
Press 〖Freq Ratio〗and 〖Freq Diff〗softkey to specify the desired frequency ration and frequency
difference. The frequency coupling relationships of two channels are as below,
CHB frequency = CHA frequency×frequency ratio + frequency difference
Press the 〖Freq Cpl On/Off〗 softkey then select Off, the frequency coupling end.
