Measurements
The TLS 216 Logic Scope not only displays graphs of voltage versus time, it
also can help you measure the displayed information. (See Figure 2-8.)

Measurement Classes
The logic scope provides three measurement classes. They are: graticules,
cursors, and automated measurements. Each of these classes, or tools, can
measure individual waveforms in any waveform group you select.
Graticule measurements provide you with quick, visual estimates. For example,
you might look at a waveform amplitude and say “it is a little more than
100 mV.”
You can perform simple measurements by counting the number of major and
minor graticule divisions involved and multiplying by the scale factor.
For example, if you counted five major vertical graticule divisions between a
minimum and maximum values of a waveform and knew you had a scale factor
of 100 mV/division, then you could easily calculate your peak-to-peak voltage:
5 divisions
×
100 mV/division = 500 mV.
