The Rigol DS1052E

Simon:
you did it ? converted a DS1052E into a DS1102E ? brilliant !!! (or did I not read between the lines properly ?)

At least, the SYSTEM INFO page states so  ;D, and when you look at this I would say YES!:

* the lowpass switching diode (I did not find a SMD part with "FC" mark, but I guess now it's only a switching diode) is reverse biased with around 5V when BW limit is OFF (see diagram, it was forward biased with 100mV before...!)
* the timebase goes down to 2ns/div
* an 80MHz signal shows about the same amplitude as a 50MHz signal, a 150MHz signal is attenuated by only about 5-6dB
I am not sure, if the circuit of the 1052 and 1102 are indeed identical, but for me it is identical enough  ;D

abbtech:
Nice work! I wonder what Rigol thinks about your clever hack.

I think, they don't really like it - but if some people, who never would have considered buying a DS1102 (like me), now buy a DS1052 - it is still raised profit!

Simon:
well they are still making a profit, infact I can't really see why they bothered doing what they did, as usual economics has gotten in the way. They are certainly making a profit on the 50 MHz versions or they would not sell them, basically the people that are buying the scopes for what they truly are are being charged through the nose, let me see I got my 50 MHz scope for £ 239, I left negative feedback because I decided that the trace was too noisy, he instantly agreed to a £ 50 refund if I changed the negative feedback. so I actually got it for £ 189 and I will assume that he did not loose out, so maybe the £ 50 was profit ? now the 100 MHz version was being sold for another £ 100, thats another £ 100 profit. But rigol obviously only had to develop one scope !

So when will we have some instructions on how to do this ? cmon this has got to be shared
