Voltage Parameters
Figure 6-5 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 difference between the maximum value and the minimum value 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 difference between the top value and the base value of the
waveform.
7. Vavg: the arithmetic average value of the voltage values of the waveform points
(relative to the GND). The calculation formula is as shown below.
