Is there a secret 'reset' button like this for the DS1000Z ?

Unfortunately, there's nothing "officially" documented, that I was able to find. I attempted the procedure above, but had no success.

I tried the above and it reset all the options and went back to Chinese (seems just like "Storage->Default" but it resets the language as well).

Luckily it starts up in a state where it says "Language" on the menu...easy to go to a different language.

I tried the procedure on my MSO1000Z and ended up with a constant beeping noise (as if I'd pressed the button too many times), but no reset. It's possible that I did something incorrectly. I'll give it another shot tonight after work.

It is the 5th gray button on the left (not the bottom gray button).  When you press it during power on it will beep a couple of times until the Rigol screen comes up.  Keep pressing it.  You'll know it worked when you see Chinese!

For those who have an interest in the DS4000, I have found the option codes for selecting the bandwidth .
This also sets the model type.

For example the code FAB9 will select 500Mhz, (DS405x), with all Decoders enabled.

The attached file contains all the details.

There are also two un-documented, possibly future, options called "Power Analysis" and "MA".

The option codes have been tested with firmware ver 00.02.00.00.04 and ver 00.02.01.00.03.

This was tested and is confirmed working BTW.  You can eliminate the need for Mr Krabs modified firmware and stick with stock stock firmware.  Bandwidth was NOT tested, but time base and system info look correct for 500MHz

I have a question: Does this work on a Rigol MSO4014?
