Vmin (Minimum Voltage)
The minimum amplitude. The most negative peak voltage measured over the
entire waveform. See Figure 40 on page 98.
Vpp (Peak-to-Peak Voltage)
Peak-to-peak voltage. See Figure 40 on page 98.
Vtop (Top Voltage)
Voltage of the waveform's flat top, useful for square and pulse waveforms. See
Figure 40 on page 98.
Vbase (Base Voltage)
Voltage of the waveform's flat base, useful for square and pulse waveforms. See
Figure 40 on page 98.
Vamp (Amplitude Voltage = Vtop - Vbase)
Voltage between Vtop and Vbase of a waveform. See Figure 40 on page 98.
Vavg (Average Voltage)
The arithmetic mean over the entire waveform.
Vrms (Root-Mean-Square Voltage)
The true root-mean-square voltage over the entire waveform.
