In my clock kit manual, Hans says to use a clean well regulated power source. I grabbed a 5v switcher from the collection and since it was running 5v with or without the load I went with it.
Sense I just bought an Oscope I decided to learn how to measure ripple, etc, and learned that I had a better option in the junk box with a linear supply. But I dont know what the characterization of a "clean" power source is, what consequences result from a dirty supply are and so on. How clean does the clock supply need to be?
My Meanwell lrs-150-12 and -24 are rated at 150-156mv p-p at 20mhz with 12 inch twisted pair terminated with 47uf and 0.1uf caps.
Is this considered clean enough for the clock and qcx, 50w amp rigs? It seems to be. My 5V wall wart measures better that this on the scope with a similar setup.
