In this video we take measurements of the inputs and outputs of a basic 2nd order active Low Pass Filter using a USB oscilloscope. Using these measurements, we produce a "Bode" style plot using Excel, or similar spreadsheet software.
Thank you for the video and lesson. It is interesting how to wire up the oscilloscope to test the Sallen-Key circuit. I will take a look at the Pico Oscilloscope and see if I can do HF circuits with it.
