thank you Sean. I work every day with Oscilltors and your info of phase noise is very clear. please continue more on RF, Oscillators, Phase Noise, Jitter, PLL, Feedback System etc...

what are the condition to obtain low phase noise for oscillator?

Sean Fedorko Thank you for your video. I just have question that if the phase noise is the area under the curve, why does it have negative value? And if it is more negative, what does it mean (ie, oscillator is worse or better)?

When you talked about Oscillator, what exactly is the signal? And what's the signal you talked about when you said "The signal would be vertical line" Thank you.
@blileytechnologies26254 жыл бұрын
Hi there! Thanks for your questions. We were referring to oscillators in general, so not an oscillator at a specific frequency (doesn't matter in this case). As for vertical line, we mean that it's ideal for an oscillator to operate at 1 very specific frequency over time (one vertical line on the graph. However, this is never the case and oscillators will always have some sort of other noise (phase noise) present. A main part of the oscillator's job is to minimize this phase noise. Hope this helps!

To measure a specific frequency at the ideal phase noiseless signal, you will still have a skirt as the measurement device will also have a bandwidth that would need to be considered and would be seen as a "measurement noise floor". As the spectrum analyzer sweeps towards the carrier frequency, the bandwidth of the receiver will start to register a signal and the skirt will be seen rising and falling as the sweep crosses the signal. The analyzer noise will also have noise that needs to be understood. To improve the measurement over a regular spectrum analyzer sweep, there's what's known as a quadrature lock between a known good reference and the device under test. Very accurate measurements can be seen at that point and a determination as to whether the device under test is worthy of the specification.
