And in that situation, one can argue that slowing down the front end to match the capabilities of the slower ADCs is a good thing for customers--you don't pay the 3 dB noise penalty for bandwidth you can't use.

(There are occasions when it's morally wrong to charge the 'fair' price so defined, e.g. cornering the market in food during a famine or other nasty monopoly behaviour--but it's a real stretch to put Rigol in _that_ category.)

Although that 20 vs 50 MHz nonsense doesn't really make any difference and probably not worth hassle. But, why varicap and that lousy circuit? Looks like Rigol analog designers don't have a clue...

I hope that people won't hack my products and steal my engineering investment. And 50 MHz is a good place for a bench scope, clear of a lot of FM and TV crud. The Rigol looks great at 50 MHz, but noisy and ringy at 100. John

And the way he did it is probably criminal conspiracy to commit a computer crime, by US law at least. So, why did he do it, specifically why did he post a video showing the whole world how to do it? He had to know it would cost Rigel real revenue, and must have decided that they didn't deserve that revenue. Jones? Why? John

After all, Intel makes less money on the lower clocked CPU chips - is this depriving Intel from deserved revenue? Note that I'm not making any judgment on whether this is right or wrong...

It is certainly the same die as the 4 core processor but it may not have passed all the tests. If you're upset at paying more for the same die, you don't even have to go as far as different number of cores. Any CPU you buy today (from AMD, Intel or IBM etc.) has different speed versions with different pricing while it's exactly the same die.
