Taking Measurements
The oscilloscope displays graphs of voltage versus time and can help
you to measure the displayed waveform.
There are several ways to take measurements. You can use the
graticule, the cursors, or an automated measurement.
Graticule
This method allows you to make a quick, visual estimate. For
example, you might l ook at a waveform amplitude and determine
that it is a little more than 100 mV.
You can take simple measurements by counting the major and minor
graticule divisions involved and multiplying by the scale factor.
For example, if you counted five m ajor vertical graticule divisions
between the minimum and maximum values of a waveform and
knew you had a scale fa ctor of 100 mV/division, then you could
easily calculate your peak-to-peak voltage as follows:
5 divisions x 100 mV/division = 500 mV.
