The automatic measurement of voltage parameters
The VDS series oscilloscopes provide automatic voltage measurements including Vpp, Vmax, Vmin, Vavg, Vamp, Vrms, Vtop, Vbase,
Overshoot and Preshoot. Figure below shows a pulse with some of the voltage measurement points.
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 VDS 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 shows a pulse with some of the time measurement points.
Rise Time: Time that the leading edge of the first pulse in the waveform takes to rise from 10% to 90% of its amplitude.
Fall Time: Time that the falling edge of the first pulse in the waveform takes to fall from 90% to 10% of its amplitude.
+Width: The width of the first positive pulse in 50% amplitude points.
-Width: The width of the first negative pulse in the 50% amplitude points.
Delay 1→2 : The delay between the two channels at the rising edge.
Delay 1→2 : The delay between the two channels at the falling edge.
+Duty: +Duty Cycle, defined as +Width/Period.
-Duty:-Duty Cycle, defined as -Width/Period.
