Neat.

Rigol continues to up the game in hacker friendliness...

"Sizzle" implies something cool or desirable. I think the word "gimmick" might be more appropriate here.

It's from an old sales idiom - "it's got the sizzle without the steak". The illusion of cool or desirable for people who don't look closely. Weird that they think that works on engineers.

Interesting, I was unaware of that. Slower than the competitive Tek models if only measuring 1-2 channels, but then faster for all at once.

16GS/s is plenty even for 6GHz version.

Not for every use case. It's been a complaint I have about KS vs Tek/Lecroy in this regard for these level scopes. If you're looking at things that are well approximated by a sin(x)/x, then 2-3x Nyquist is fine. If your waveform is more complex, you need more points, no getting around it.

5X Nyquist might seem better, but 2,5-3x Nyquist is always fine. Demanding 32GS/s for 6 GHz bandwidth scope will get you nothing special except much higher price.
If you waveform is more complex you need more bandwidth in a first place. So maybe a 10 GHz scope.. Or more.
But at these kinds of speeds, signals look differently. It is hard to make a perfect square wave. Signal is limited in bandwidth by definition. As you reach certain speeds, the passive backplane starts becoming very good lowpass filter. Your interconnect has limited bandwidth. There are no perfect sharp edges in there, relative to repetition rate...

Look out in your company parking lot. How many engineers' cars are "cool" and/or "desirable"? - a fair proportion, I would guess! QED :D

Bottom line: A fully loaded system is probably going to be close to 100,000 bucks.
I'll wait a few years until they go for $5000 on eBay.

Which hobbyist is prepared to to spend on a monster scope that consumes 500 Watts? Admitted, there have been Tektronix "tube coffins" that had similar consumption but I'ld consider that way too much, especially since an instrument like this probably wouldn't like to be power cycled too frequently. That instrument is clearly aimed at professionals...
