Owon HDS25 - The Automatic Measurement of Voltage Parameters

16
9 types of measurement can be displayed at the bottom left of the screen.
For bandwidth ≤100MHz models, automatic range types include Frequency,
Period, Amplitude, Maximum, Minimum, Peak-to-Peak value, Mean, and
RMS.
For bandwidth 200MHz models, automatic range types include Frequency,
Period, Amplitude, Maximum, Minimum, Peak-to-Peak value, Mean, RMS,
Rise Time, Fall Time, +PulseWidth, -PulseWidth.
The description of the automatic measurement Function Menu is as follows:

The automatic measurement of voltage parameters
The oscilloscopes provide automatic voltage measurements including
Mean, PK-PK, RMS, Max, Min and Vamp. Figure 3- 9 below shows a pulse
with some of the voltage measurement points.
