Match the settings of the input coupling (i.e. AC-GND-DC) switches on the oscilloscope to their functions.

Display the reference line or zero base line on the oscilloscope screen from which all CH2 measurements are made. It does NOT ground the input signal but instead blocks the entire CH2 input signal so that only a flat line is displayed on the screen.

Blocks the dc component of the CH1 input signal using a capacitor inside the oscilloscope at the CH1 input system. Thus only the ac (alternating current) component of the CH1 input signal is coupled to the CH1 vertical deflection and signal acquisition systems, and thus only the ac component is displayed on the screen.

Blocks the dc component of the CH2 input signal using a capacitor inside the oscilloscope at the CH2 input system. Thus only the ac (alternating current) component of the CH2 input signal is coupled to the CH2 vertical deflection and signal acquisition systems, and thus only the ac component is displayed on the screen.

All frequency components (ac and dc components) of the CH1 input signal are coupled to the CH1 vertical deflection and signal acquisition systems, thus displaying the entire signal on the screen.
