Measurements
2. Vmin: indicates 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: indicates the voltage value from the flat top of the waveform to the GND.
5. Vbase: indicates the voltage value from the flat base of the waveform to the GND.
6. Vamp: indicates the voltage value from the top of the waveform to the base of the
waveform.
7. Vupper: indicates the actual voltage value that corresponds to the threshold
maximum value.
8. Vmid: indicates the actual voltage value that corresponds to the threshold middle
value.
9. Vlower: indicates the actual voltage value that corresponds to the threshold
minimum value.
10. Vavg: indicates the arithmetic average value on the whole waveform or in the
gating area. The formula is shown as follows:
Wherein,
11. VRMS: indicates the root mean square value on the whole waveform or in the
gating area. The formula is as follows:
Wherein,
points being measured.
12. Per.VRMS: indicates the root mean square value within a period. The formula is as
shown above.
13. Overshoot: indicates the ratio of the difference between the maximum value and
the top value of the waveform to the amplitude value.
14. Preshoot: indicates the ratio of the difference between the minimum value and
the base value of the waveform to the amplitude value.
15. AC RMS: indicates the root-mean-square value of the waveforms, with the DC
component removed. The formula is shown as follows:
