Welcome to this installment of EE Classroom on Testing Basics!
For all the various components and systems that are part of our Learning Center classrooms, their one common denominator is the absolute requirement for testing. The complexity of electronic devices, and the emerging technologies such as 5G, artificial intelligence, machine learning, mean every step of device design must be tested thoroughly. From a humble probe to a spectrum analyzer, testing hits every level starting with R&D and ending with certification.
While my EE Dad thought his oscilloscope in the hallway was a practical, green-glow nightlight for my siblings and me (it was about 1000 times the size of nightlight five decades ago), the true purpose of the oscilloscope keeps it on the forefront of test and measurement activities. In this classroom, you’ll find some helpful oscilloscope basics, as well an overview of other electrical measuring instruments. This includes spectrum and network analyzers and some of various measurements you can make with both. And nothing like a bit of Fast Fourier Transform articles to spice up your learning day.
And, hey, unlike some devices you are testing…these classes aren’t Pass/Fail.

The probe tip extends from the end of the insulated probe body, which serves as a handle and also contains components and circuitry specific to the probe type.
Our contemporary digital oscilloscope has far fewer front-panel controls and typically employs multipurpose knobs that are contextual.
Here’s a quick review of some basic instrumentation common to most engineering work benches.
