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.
The automatic measurement of time parameters
The SDS series oscilloscopes provide time parameters auto-measurements
include Frequency, Period, Rise Time, Fall Time, +Width, -Width, Delay 1
