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 , and Duty cycle.
