Preshoot And Overshoot Measurements - HP 1652B Getting Started Manual

Preshoot and
Preshoot and Overshoot measure the perturbation on a waveform
Overshoot
above or below the top and base voltages (see "Top and Base Voltages"
Measurements
section earlier in this chapter). These measurements use all data
displayed on screen, therefore it is very important that only the data of
interest be displayed. If you want to measure preshoot and overshoot
on one edge of a waveform, then only display that edge. If you want to
measure the maximum preshoot and overshoot on a waveform, then
display several cycles of the waveform.
Preshoot is a perturbation before a rising or a falling edge and is
measured as a percentage of the top-base voltage. Overshoot is a
perturbation after a rising or a falling edge and is measured as a
percentage of the top-base voltage
If the measured edge is rising then:
Preshoot = r -1 X 100

Overshoot = I Vmaximum - VtoD 1 X 100

If the measured edge is falling then:
