1. Vertical resolution for 8 bits = 0.4% of full scale, for 12 bits = 0.024% of full scale.
2. Full scale is defined as 8 vertical divisions. Magnification is used below 7.5 mV/div. Below 7.5 mV/div, full-scale is defined as 60 mV/div. The major scale settings
are 5mV, 10mV, 20mV, 50mV, 100mV, 200mV, 500mV, and 1V.
3. Input impedance is valid when V/div scaling is adjusted to show all waveform vertical values within scope display.
