content: I just recently came across a rubidium oscillator in that format while browsing, I forget who made it but the price was almost $2k.There's also a chip scale cesium atomic oscillator made by Microsemi, but those are over $5k currently.It's the sort of thing that could potentially cost peanuts a decade from now though, I remember when green DPSS lasers were over $2k and now you can get those for under $5 from China.

content: Sigh...I really need another rabbit hole to explore, but I'll give them a call. Meanwhile this was the result of a morning email from a friend in the UK asking about U6.https://www.eevblog.com/forum/rf-microwave/another-ebay-noise-source/msg3035730/#msg3035730Sort of got a lot of egg on my face with the initial post, but still a nice piece of low cost RF kit. I just need to bodge in a couple of better regulators so it will run on a wider range of input voltages. But it's a lot better than the BG7TBL version.Have Fun!Reg
