Sniffing the Rigol's internal I2C bus
Strada916:
Many thanks to the people that made this happen. Learning all the time. DS1074ZS to DS1104ZS.

yes, the model # changes but this does NOT make the scope work any faster. the bw is still the same, from what I've seen.
I know my sig gen is flat to 250mhz and so doing a test at the 100mhz level is pretty trustworthy. I just did not see any diff in cutoff from before and after the upgrade. model # did change, no argument there, but it was a 70mhz scope before and its still a 70mhz scope, now.

Thanks. I was more after the other options anyways. But thanks

same here. I bought the 4ch scope for its proto decode, storage and views. 70 to 100mhz means nothing, especially since I was able to see waveforms at 250mhz very easily.
Orange:
I have an original DS1104Z, and the B/W is about 125MHz (-3dB). The build in hardware counter works OK till 110Mhz, if you go higher it gives unreliable results.
Perhaps RIGOL has done some other limiting to prevent B/W upgrades on the 70MHz model.....
I still think this is an amazing piece of test gear for the money....especially if you add the triggers, decoding and memory options :)
