Where does jitter come from?

[Bricolo]

I'm just curious... 🙂

I'd like to make some measurements on my KC-7

Can jitter be measured with some "basic" test equipment?
I have access to a 60MHZ digital scope with FFT, and maybe to a 24GHz spectrum analyser

Hi

No, you can't, if jitter gets into ps range the time base of the scope is not acurate enough

You'll need something like a Wavecrest 3000, or a another setup with a mixer and reference oscillator

I doubt thay my university has such test gear 🙁

do you think any of those memebers involved in clocks, even those who make money selling them, has?

Hi

I have an HP53310A time domain analyser at my own (Tent)lab, and have access to a Wavecrest 3000.

cheers
