Rabbit Hole: Phase Noise Measurement Challenges - UNI-T UTG962E Function/Signal Generator

https://www.youtube.com/watch?v=hBDGztAnfI4

In this video:
I take a look at trying to measure the phase noise of the UNI-T UTG962E vs my TTi TG2511A. I explain and show what's involved in phase noise measurement, the cost involved...and then a method I came across to do the comparison. (open for debate)

Older Technology / Re: Some really old electrolytic capacitors

Well, it is old enough to be on pension, and I have some equally old TO3 transistors as well, OC36, equally old, but with absolutely nothing on them other than the type stamp. PNP 32V 8A, with a whole 30W of power dissipation.
