Test Instruments

When you build an experimental circuit, you will generally need to have some way to determine whether or not it is working correctly, and if so, how well. If it is not working, you'll need to locate the problem so you can fix it. To accomplish this, a wide range of test instruments has been developed. Some of these apply to many different kinds of circuits, while others are specific to one type or class of circuits.

This page lists the more common types of test instruments that you may want to use with these experiments, with descriptions of what they do and where they are useful. Some of them will be the subjects of experimental circuits themselves, so you can actually experience how they work and what they do. Others are beyond this scope, or are not feasible as experimental circuits.
