The purpose of this board is to learn how to perform basic measurements with an 

oscilloscope. Most experiments can be performed with any digital storage scope. Some 
experiments can be performed with an analog scope. 
Experiments in this project are performed using the 

Velleman HPS140 Handheld Pocket

 

Scope. All experiments require basic knowledge of terms such as AC and DC voltage, cur-
rent, resistance, etc… 
Make sure to check You Tube as well, it features a short movie for each experiment.
