Noise is a common problem for electronic circuit design and when acquiring signals using an oscilloscope. Noise comes from various sources, both internal or external to your design, obscuring your signal of interest. A clean trace on your oscilloscope that is free from noise allows you to focus on the “right” signal.
All Tektronix oscilloscopes, including the basic oscilloscopes we’ll be discussing in this post, provide capabilities to help you deal with noise. Here are three that are particularly useful.
