Member: 38731 Status: Offline Thanks Meter: 0 | The screen of a scope is covered with vertical and horizontal lines for easy measurement. This is called the Gratiscule A dot of light takes time to go horizontally from point A to B this is the timebase. The faster it goes thedot of light leaves a trail and eventually a line called a TRACE. Vertical adjustment is the measure of voltage per box section so if a trace was inthe middle and you put 1 volt input and the vertical is set at 1volt per division it will jump one box line. Timebase X Voltage in equals frequency Paul |
