rOmV4 - Measure Oscilloscope

Oscilloscopes are used to measure time, voltage and wave shape. By calculation, frequency can be measured too.

Wave Terminology

In this image the peak voltage is 4 Volts and the wave period is 1.3 ms. The frequency = 1 / 1.3ms = 770Hz.

Traditional Oscilloscope

This is a fairly typical example of a complex measuring instrument. Top end instruments cost £20 000!

USB Connected Digital Scope

Top end USB oscilloscope can be expensive but there are many capable budget models like this one which doubles up as a signal generator.

Here is a Picoscope screen display - photoshopped after capturing the wave shapes.
