The automatic measurement of voltage parameters
The DS1000CA series oscilloscopes provide automatic voltage measurements
including Vpp, Vmax, Vmin, Vavg, Vamp, Vrms, Vtop, Vbase, Overshoot and Preshoot.
Figure 2-110 below shows a pulse with some of the voltage measurement points.

Voltage parameters
Vpp: Peak-to-Peak Voltage.
Vmax: The maximum amplitude. The most positive peak voltage measured over the
entire waveform.
Vmin: The minimum amplitude. The most negative peak voltage measured over the
entire waveform.
Vamp: Voltage between Vtop and Vbase of a waveform
Vtop: Voltage of the waveform’s flat top, useful for square/pulse waveforms.
Vbase: Voltage of the waveform’s flat base, useful for square/pulse waveforms.
Overshoot: Defined as (Vmax-Vtop)/Vamp, useful for square and pulse waveforms.
Preshoot: Defined as (Vmin-Vbase)/Vamp, useful for square and pulse waveforms.
Average: The arithmetic mean over the entire waveform.
Vrms: The true Root Mean Square voltage over the entire waveform.
