This slide shows the vertical parameters, from the minimum to the maximum, and includes overshoot and undershoot. The amplitude is measured from the base to the top, and does not include overshoot and undershoot. When measuring rise time, for example, it will be measured from 10% to 90% of the rising edge, and fall time is measured from the 90% to 10% of the falling edge. There are also user definable levels which allow the user to measure rise and fall time in any desired portion of the waveform.
