FesZ Electronics | Crystal oscillators - Negative resistance and oscillation margin measurements @FesZElectronics | Uploaded September 2021 | Updated October 2024, 5 hours ago.
#134 In this video I continue looking at quartz crystal oscillator related measurements by taking a closer look at the negative resistance measurement. I look at what this measurement means, and how it can be turned into a more useful parameter which is the oscillation margin. Finally I look at what sort of possibilities there are when you run into problems with the measurement results.
