Measure System
The oscilloscope displays the voltage in relation to time and tests the
waveform displayed. Different measurement techniques such as scale,
Cursor and auto measure modes are used.
Scale Measurement
This method allows you to make a quick, visual estimate. For example, you
might look at 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 major vertical graticule divisions between
the minimum and maximum values of a waveform and knew you had a
scale factor of 100 mV/div, then you could easily calculate your peak-to-
peak voltage as follows:
5 𝑑𝑖𝑣𝑖𝑠𝑖𝑜𝑛𝑠 ×
100 𝑚𝑉
𝑑𝑖𝑣𝑖𝑠𝑖𝑜𝑛
= 500 𝑚𝑉
Cursor Measurement
Press the “CURSORS” button to display the “Cursor” menu.
The cursor measurement has three modes: Manual, Track, and Auto
Measure.
