DC/AC/GD

Using the "DC/AC/GD" switches, the input coupling off a channel can be selected.

In position "AC" (=alternating current coupling) the signal is RC-coupled. Its DC component is filtered. In position "DC" (=direct current coupling) the DC components are not filtered.

The position "GD" (="Ground") shortens the signal input connector, which results in a horizontal line on the screen as between ground and signal not voltage potential remains (in the simulation this always equals 0 V input level).

Despite the fact the theoretically any type of signal can be loaded into a simulated signal cable in the simulation software, the simulation as shown is limited to pure sinus signals. The switch position "DC" therefor generates the same output as the switch position "AC".
