The oscilloscope is arguably one of the most useful general purpose tools ever created for use by electronic engineers. Since its invention more than 100 years ago, new types, features and functionalities have been introduced.
As automated measurements become ever more complex, many of the key considerations, such as probing, sampling, vertical and horizontal system, and trigger stability remain the same. It’s therefore important for the user to understand the underlying technology to get the most benefit out of his or her oscilloscope.
This primer provides an overview of the basic, but most important building blocks of an oscilloscope as it relates to specifications, limitations and impact on measurement accuracy.
