here is a spectrum analyzer, inexpensive, works with any scope or optionally works with the computer sound card, still mostly analog, as a kit or as completed modules:

Are FETs supposed to glow like that?

Only about $500, plus time to assemble, put in an enclosure.....

Some cool features...

But I really like in the desciption of it's features and design principals, it says:   " Isn't half a loaf better than none?.. "

I bought the various kit pieces back in the early 90's at Dayton. By early Saturday afternoon, they were sold out of everything. The complete design was part of a Ham Radio Magazine article(s) back in the 70's. Worked fine for what it was. Still have it around here somewhere. Use it with a Tek 465 scope.

It's all in the case, the presentation. It is left to the builder to make the case as he sees fit. Except for the case shown on the website, others I found didn't thrill me much. It was almost like the builders just threw the guts in a box. Maybe I missed a real nice looking one though. Might be kind of cool in a heavy 1/4" aluminum rackmount with black crackle paint, chrome handles, big black knobs, and a really old school numerical display instead of the LCD. There is an aircraft instrument somewhere that has a "999 plus tick marks" set of reels inside. A retrospectacle.

We were talking before about hurting the Mercury receiver front end with static, etc.  Here's a post about a guy who put 16 watts into a Mercury for 30 seconds.  They appear to be pretty robust.
