OWON HDS1021M Handheld DSO & DMM 8-Advanced Function of Oscilloscope

Term interpretation

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.

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.

+Duty: +Duty Cycle, defined as +Width/Period

-Duty: -Duty Cycle, defined as -Width/Period.

8.10 Setting the Cursor Measurements

This oscilloscope allows you to make manual cursor measurements on time and voltage..

The cursor measurement menus are listed and described in the following table.
