1. Setting up channel coupling
Take the example of applying a signal to CH1. The signal being tested is a sine signal that
contains DC %.
Press [F1] then [F2] to select AC. It is now set up as AC coupling. DC quantities of the
signal being tested will be intercepted. The waveform display is as follows :
Figure 2-1 DC quantities of the signal are intercepted
Press [F1] twice to select DC. Both DC and AC quantities of the testing signal being
inputted to CH1 can pass through. The waveform display is as follows :
Figure 2-2 Both DC and AC quantities of the signal are displayed
