Produced by the National STEM Learning Centre and the Institute of Physics, this video demonstrates how to use an oscilloscope to measure potential differences that vary with time. The clip shows how to set up the oscilloscope and explains how the vertical displacement corresponds to a potential difference. The horizontal scan can be set to give different timescales. It also shows how, when attached to a signal generator, the oscilloscope can be used to demonstrate different waveforms.

This is pretty good! I use the oscilloscope quite often in class! Just one problem! The spot will not keep still on my screen! I guess it needs servicing??? Is there any way I could do this myself??? Recession and cost etc!!! Thanks
