Welcome to this installment of EE Classroom on Oscilloscopes
As a young child of an electronics engineering father, I became first acquainted with an oscilloscope while stumbling to the bathroom at night. The green glow emanating from an instrument about the size of an end table kept the otherwise dark hallway bright enough. The true purpose of this irreplaceable device no longer escapes me, of course, but the memory still, well, glows. Whether in a home workshop or massive engineering lab, the oscilloscope is truly beyond measure.
In this classroom, we’ll start with some Cathode Ray Oscilloscope (CRO) basics, then move into modulation tutorials from analog to digital to 5G. Walk through a checklist of what to consider when trying to achieve that ideal and accurate measurement. Wondering what it takes to measure harmonics, trace transistor I-V curves, demodulating and playing back AM signals, or decoding logic values into tangible sensor location data? Then access the related content for detailed, step-by-step projects complete with inventory, descriptions, and hardware, software and script instructions.
Hopefully, these resources shine a little light on the pathway towards your continued education.

Basics of ampitude distortion
Sources of amplitude distortion include noise and interference, but the main source of non-linear amplification and distortion can include noise sources superimposed on the waveform of interest
