Figure 4-19
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 A→B , Delay A→B , Screen Duty, Phase A→B
,
and Phase
A→B , FRR, FRF, FFR, FFF, LRR, LRF, LFR, LFF.
Figure 4-20 shows a pulse with some of the time measurement points.
