1). Set the channel coupling
To signal applied to the oscilloscope channel, for example, the measured signal is a
square wave signal containing AC component.
●Main menu, select "Universal oscilloscope" press "OK" button to enter the oscilloscope
screen.
Press "CH1" → "Coupling DC", press “F3”set to DC coupling. DC and AC
components of the input signal to pass through.
As Figure 2-4
● Press "CH1" → "Coupling AC", press “F3” set to AC coupling. DC component of the
input signal is blocked. As Figure 2-5
● Press "CH1" → "Inverse" and press the SELECT function key "F4" to anti opposite way.
