2. Set Channel Coupling

With CH1 taken for example, input a sine wave signal containing a DC offset.

Press 

CH1→Coupling→AC

 to set “AC” coupling. It will pass AC component blocks 

the DC component of the input signal.

The waveform is displayed as Figure 2-3

 

Figure 2-3

Press 

CH1→Coupling→DC

, to set “DC” coupling. It will pass both AC and DC 

components of the input signal.
