2.10. Measure System
The oscilloscope displays graphs of voltage - time and can help to measure the displayed waveform.
There are several ways to take measurements, using the graticule, the cursors or performing an
automatic measurement.
2.10.1. Scale measurement
Graticule: This method allows you to make a quick, visual estimate and take a simple measurement
through the graticule divisions and the scale factor.
For example, you can take simple measurements by counting the major and minor graticule divisions
involved and multiplying by the scale factor. If you counted 6 major vertical graticule divisions between
the minimum and maximum values of a waveform and knew you had a scale factor of 50mV/division,
you could easily calculate your peak-to-peak voltage as follows:
6 divisions x 50mV/division = 300mV.
