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.
5.13.3 Amplitude Coupling
Amplitude coupling, which is enabled by the 〖Ampl Cpl On/Off〗 softkey, couples the amplitude and
offset voltage between the channels. This means that changing the amplitude or offset on CHA will
affect CHB. Well noted that the CHB can’t be set.
Press 〖Ampl Diff〗and 〖Offs Diff〗softkey to configure the desired amplitude difference and offset
difference. The amplitude coupling relationships of two channels are as below,
CHB amplitude = CHA amplitude + amplitude difference
CHB offset = CHA offset + offset difference
Press 〖Ampl Cpl On/Off〗 softkey then select Off, the amplitude coupling end.
