These control the kind of coupling to the input: direct|\DC", through a capacitor|\AC", or disconnected|\GND". The amount of ampli cation applied to the signal is controlled by a knob, and is speci ed in terms of screen units: a \10mV/div" setting means that a 10 millivolt change in the input signal will move the trace vertically by one major ...
