Mastro Gippo:
Damn, the post notification mail didn't work, and I discovered the news just today!
I just made the mod myself, and IT WORKS GREAT!! Thanks everyone... I should add a few info about my experience:
The correct method is to changhe the serial number first, then the model number, then you can power cycle the scope. Keep your fingers away from the "enter" key!! If you press it instead of the alt+010 combination, it will add a line return at the end of the serial number. Always double check the results of the query commands before power cycling.

My father did some tests with a professional signal generator, you can see the data and graphs in the attached document. Somehow excel won't let me set the horizontal scale to logarithmic, so I left everything as-is.
I'm happy!  ;D

I did the model number then the serial number, worked fine that way round for me. I was swapping back and forth between 100mhz to 50mhz doing some testing and accidently left the E off the model number and the scope still booted up fine to my surprise. I never noticed I have left the E off the model number until I looked at the scope wondering why the model number was wrong :) It fired up with DS1102 as 100mhz ok luckily.

That's really great to see, thanks.  Very impressive performance.

Thanks for the procedure details. :)

I just wanted to include a short bit for those who don't speak Italian and may be confused by the bottom two graphs in the spreadsheet.

Canale = Channel
Differenza misura frequenza = frequency difference measurement

I take partial picture about this test xls to here. I hope Mastro Gippo accept this copy. (in copy read source info)



I want ask: What are numbers in Y scale? (My quess (becouse these shown numbers) is that they are scope measured RMS and if they are, please connect this 50ohm terminator and test agen ;) ). Sig gen output is for 50ohm load.)

What are oscilloscope settings in this measure. Same settings in whole frequency scale? (scope mV/div, equtime or realtime? x ns/div? normal memory? Sinx/x on/off?)
What is signal  exactly connection to oscilloscope inputs.  (cable type/termination? calibration or some opinion how accurate leveling over used freq range = also if it is R&S it may be fail.)

If I or somebody tell data/numbers but not tell how I get data/numbers they are nearly or just as garbage... ;)

I ask becouse there is something wrong!
there is minimum 3 posibilities:

1. Test configuration is bad? (bad cable/missing or fail termination.)
2. Your oscilloscope is fail. (not my first opinion becouse both channels equal)
3. Signal generator is fail. (leveling defect)

If all is ok with test: 1052Emod or 1102E frequency response (flatness) is never as bad as in picture. If picture freq response is true for these scopes they are just as toys or garbace stuffs. (but they are not if they work normally)

But in real: Simple, I think test configuration fails ;)
