Suggestion: Do NOT remove Options before updating Firmware!  We have never seen new Firmware that we installed remove the Options, although we have seen instances where when Firmware has been updated we were NOT able to install, or re-install the Options.

Please feel free to check this out with others here on the forum if you have doubts.

But to be safe I would NOT remove any Option unless you want to return your unit for Rigol factory repair, which by the way is very seldom ever required.  If your unit works for the first 30 days Ok it will probably last much longer than 3 years (if you don't seriously abuse it yourself).

Generally when someone returns an item for Rigol factory repair they will remove the Options for you, and in general you will never be able to re-install them yourself.  But then how bad can that be, because the Rigol gear is awesome for the price we pay for it even without the Options hijacked in.  And, you can still buy the Options if you want them bad enough.

Please don't ask me how to remove Options.  You can search for this information here in the EEVblog.  And by the way the Options Can NOT be removed by us in the 'DSA800 Series.  But don't worry, Rigol knows how to do it.  Hi Hi

Except the MSO1xxx devices which have their own patched version of Riglol and need to be JTAGed to get a memory dump.

Everything else, is everything else listed in the Keygen, and yes the MSO01xxx is NOT listed or covered by either or any Keygen version to date.

Ah ok, I didn't understand it that way. However, many people seem to mistakenly think that the DSO1xxx hacks will work on the MSO. I've seen many comments (on this blog and others) assuming that that's the case.

Trax:
Is the only difference with regard to hacking between the MSO01xxx and the DSO01xxx that for the MSO a J-Tag memory dump is needed?
Or is there something else thats different?

except the new firmware for the AWG DG4062, if you set to 200mhz (a model they didnt sell) the new firmware reverts it to 60mhz, if you set it to 150mhz it will stay.

except the new firmware for the AWG DG4062, if you set to 200mhz (a model they didnt sell) {Because it was never even offered by Rigol; *Ted5472} the new firmware reverts it to 60mhz, if you set it to 150mhz (correction - 160MHz*) it will stay.

This was an exception, because this was never a Rigol offered capability (or as we incorrectly referred to it, a Option).  See -> https://www.eevblog.com/forum/testgear/dg4000-a-firmware-investigation/msg581608/#msg581608  (DG4000 Firmware thread, Post #270)
It still stands that 'We have never seen new Firmware that we installed remove the Hacked in Options'.  Again, 160MHz was never an Option, although the capability was discovered and found how to get it, it was not fully functional to the Rigol, i.e. the amplitude flatness specifications as were the valid frequency BWs that were available from Rigol.  And it took some special tricks with the DG4000 calibration to get it to be decent.  Which is also documented by me and others in the DG4000 Firmware thread.
