Even if we were stuck with just today's technology forever it would get extremely cheap over time, and with gradual saturation implementation of computing and every known trick, resulting performance would still go up. NT

If by that obscure reference you advert to my 9 oscilloscopes, I can assure you, Sir, that I can take them or leave them alone. ;) Just got in an HP 70820A Microwave Transition Analyzer, which is a DC-40-GHz sampling scope/ spectrum analyzer / network analyzer / dynamic signal analyzer. They go for really cheap (this one was $775) because nobody knows what they are.

Ummm, I have about 60 oscilloscopes now. That's perfectly normal, isn't it?

I've got one, but I've yet to unpack it. Sixty would have been hard to fit = into the biggest house we ever owned

Not entirely. I know enough about what it is to know that I need one about = once per decade, and that it would make sense to hire it then, rather than = tying up storage space for ten years between uses. --=20 Bill Sloman Sydney
Yeah, but you have to share yours, whereas I get to Gollum, I mean Bogart, mine. ;)

The older stuff is collectables, not shared or much used any more. 535s, 545s, 547s, 5000 series, 7000 series, a few really old Teks, tons of plugins. I learned picosecond stuff with this flea-market Tek 1S2: https://dl.dropboxusercontent.com/u/53724080/Gear/1S2/1S2.jpg And some HPs, including an HP185 with plugins, the first really modern sampling scope. https://dl.dropboxusercontent.com/u/53724080/Gear/HP/HP185/HP185.jpg https://dl.dropboxusercontent.com/u/53724080/Gear/HP/HP185/training2.jpg I have a histororical, but really crappy, Lumitron sampling box, intended to be used with a separate oscilloscope.
