DS1000Z - remove the 500uV option - it does NOT work. It will let you go to 500uV but will push the signal low off the screen. I also don't think there is a bandwidth difference between the 70MHz and 100Mhz models - my rise test test shows >200MHz. See post #32 here:

Alan, did you perform a SelfCal, and that didn't correct the shift?

That is true, you have a good point, let me try that!
Frequency Response Plots for DS2000 series 300Mhz firmware.
While doing these measurements I found that with Ch1 and Ch2 turned on, the displayed waveform does not change when switching between 1nS and 2nS/div. It is displayed as 2nS/div. The time/div readout changes but the only change to the displayed wave form is the trigger point.
If there is a frequency measurement active on the screen, it will read double the correct value when on the 1nS/div range.
The hardware freq counter reading remains correct .
With only one Channel turned on, all is well.

My ds2072 (hacked to 200mhz) not update to ds2302 (300mhz), i bought other pendrive that was detected, but i haven't success again.
Can anybody help me ?
Thanks
I have not had time to test every feature, just got my DS1084Z-S today. Have you done the Self-Calibration after enabling 500 uV option? My unit had significant DC offset from factory, that disappeared after Self-Calibration.
Ok, I'll try uninstall the keys, but i dont know to do this.
I'll research the procedure to uninstall too.
Thanks Cybernet for your help, great work.

Interesting. Even after a self cal switching to 500uV for me pushed the signal off the screen... Maybe you have hardware that supports it and mine does not...

Just to clarify, I have not enabled 500 uV/div resolution on my scope. But I had ca. 0.5 div offset on 1 mV/div from factory, and that corrected it self quite well after self cal.
