Dave has simply exposed a scam and there is nothing Rigol can do legally. ...... Phil

Now that customers are informed they can make a choice based on knowledge. Rigol were obtaining benefit from a deception and that is criminal behaviour in any place outside China. > The moral thing would be to have announced that "We have discovered that > the two instruments are electrically identical, and it is possible to > modify the 50MHz version, in firmware, to behave identically to the 100MHz > version.

Been there and done that many times. ...... Phil

I think that _is_ interesting. Discuss it, please. Jon

I find that funny considering it was you who started the ranting and also continued it ad nauseam. So why don't you just stop ranting and actually discuss that technical aspect if it interests you? Or is this just your way of trying to weasel out of the rather silly hole you found yourself in? :-> Dave. -- --------------------------------------------- Check out my Electronics Engineering Video Blog & Podcast: http://www.eevblog.com |
