I'll keep my W&G SNA-33. 20Hz to 26.5 GHz with 1 Hz filter BW. And a fundamental mixer. Not those noise steps from range to range like these old HPs when they switch to the next harmonic.

Your great uncle Cursitor Bradford Beauregard Doom the 3rd prolly worked on it already that's why there's a 2.2 uF electrolytic where it shouldn't be and it still don't work.

Yeah... We call that troubleshooting.
Sometimes it is a large, expensive component. :-)

I am sure the boys at ViaSat have figured out just about all there is to know about SDR root hardware. Our mil boys enjoy about ten different SDR generated (and received) waveforms. Haven't seen many complaints.
Link16 has been around for a long time. So have many of the others.
Sounds like an extremely nice box, but also very obscure, at least over here. I wonder why they weren't more popular. Any obvious drawbacks? Can you get schematics?

Yeah, being very obscure! :-D

It has some 56001 and a yig preselector and yes, it runs DOS 5 on its embedded AM386.
<The drawback was the price.
cheers, Gerhard
My old HP 70000 analyzer was like that too, including the 1-Hz IF bandwidth, but then it was a 15+ year newer design. The 8566 series is now 40 years old. When was your W&G unit introduced?
Cheers
