Voltage Parameters
1. Vmax: the voltage value from the highest point of the waveform to the GND.
2. Vmin: the voltage value from the lowest point of the waveform to the GND.
3. Vpp: the voltage value from the highest point to the lowest point of the
waveform.
4. Vtop: the voltage value from the flat top of the waveform to the GND.
5. Vbase: the voltage value from the flat base of the waveform to the GND.
6. Vamp: the voltage value from the top of the waveform to the base of the
waveform.
7. Vavg: the arithmetic average value on the whole waveform or on the gating
area.

9. Overshoot: the ratio of the difference of the maximum value and top value of
the waveform to the amplitude value.
10. Preshoot: the ratio of the difference of the minimum value and base value of
the waveform to the amplitude value.
