The automatic measurement of voltage parameters
The oscilloscopes provide automatic voltage measurements including Mean,
PK-PK, RMS, Max, Min, Vtop, Vbase, Vamp, OverShoot, PreShoot, Cycle RMS,
and Cursor RMS. Figure 5-71 below shows a pulse with some of the voltage
measurement points.
Figure 5-71
Mean: The arithmetic mean over the entire waveform.
PK-PK: Peak-to-Peak Voltage.
RMS: The true Root Mean Square voltage over the entire waveform.
Max: The maximum amplitude. The most positive peak voltage measured over the
entire waveform.
Min: The minimum amplitude. The most negative peak voltage measured over the
entire 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.
Vamp: Voltage between Vtop and Vbase of a waveform.
OverShoot: Defined as (Vmax-Vtop)/Vamp, useful for square and pulse
waveforms.
PreShoot: Defined as (Vmin-Vbase)/Vamp, useful for square and pulse
waveforms.
Cycle RMS: The true Root Mean Square voltage over the first entire period of the
waveform.
Cursor RMS: The true Root Mean Square voltage over the range of two cursors.
The automatic measurement of time parameters
The oscilloscopes provide time parameters auto-measurements include Period,
Frequency, Rise Time, Fall Time, +D width, -D width, +Duty, -Duty, Delay
