5. Advanced User Guidebook
Vpp, Vmax, Vmin, Vavg, Vamp, Vrms, Vtop, Vbase, Overshoot and Preshoot.
Fig.5-45 below shows a pulse with some of the voltage measurement points.
Fig.5-48
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→2 ,Delay 1→2 , +Duty and -Duty.
Figure 5-46 shows a pulse with some of the time measurement points.
