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 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. Vupper: the actual voltage value corresponding to the threshold maximum
value.
8. Vmid: the actual voltage value corresponding to the threshold middle value.
9. Vlower: the actual voltage value corresponding to the threshold minimum
value.
10. Vavg: the arithmetic average value on the whole waveform or on the gating
area. The calculation formula is as follows:
i
x
Average =
n
∑
(6-2)
Wherein,
i
x
is the
i
th point being measured,
n
is the number of points being
measured.
11. Vrms: the root mean square value on the whole waveform or the gating area.
The calculation formula is as follows.
12. Per.Vrms: the root mean square value within a period. The calculation formula
is as follows.
