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.

Without any official documentation or insider information, I think the only way to discover or find features like this would be to disassemble the firmware image and trace code paths. I'm taking a stab at this right now, but have a steep learning curve ahead.

Reset procedure for DS2000/4000/6000, to be confirmed for DS1000 series.

DS4000 series Bandwidth (model type) Option Codes.

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.

*EDIT*
 Attached updated PDF document to include the option selection codes for LIN and 1553B decode.
Also included are two possible future options,  Power Analysis and I2S decode.
Power Analysis has been listed for some time, but the I2S decode is relatively recent.
The original un-documented "MA" option has become the 1553B decode option.

Well thats cool, how did you find these extra ds4000 options? Why do you think they weren't discovered before?

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.
