It looks like from the screenshot you have found an other hidden menu, where you can enter the scope model, serial number, and fan speed !
Question now is how to get there
No, I have not found how access to the hidden menu, if it exists. I wish.
Is only that I think there is the possibility to modify the S/N modifying the firmware. And it may only work in some cases, I have not tried.
The capture Hidden_Menu.JPG only shows the ASCII strings of a possible menu.
I thought I read somewhere in this thread where you can access the hidden menu via certain keystrokes. I may be wrong or maybe dreamed it, lol. I will look again and if I find it I will quote/repost here
The keystrokes must be simple and accessible by 4 finger press usually from my experience. I will try and hack it and let you know if I am successful. Cheers
Please someone who has had the problem with the S/N:
What S/N have you used to install the options, after the "failure", DS2A0...01 or original S/N?
after failure, original will no longer work, must use the sn reported on info screen.

Now look at this picture:
EEVBLGTECHNOLOGIES??? DS2A140000000???
cybernet: How did you do that?
ds1000z seems to use the same ecc parameters and private key as the DS2000, so the rikey.c should work (with the ds2000 priv key).
option bits are unknown as i have not yet seen a trial or official key - somebody should try it.
ds1000z seems to use the same ecc parameters and private key as the DS2000
where you got that? Not from firmware, so i assume you checed PC sw?
So, can you change the FFT trace color ?

a user PM'ed strings <firmware.GEL> - curve parameters, primes all the same - public key is different, but derived from the same already known private key, they just used another seed value to generate it - so i believe it will work out of the box with the DS2k keygen.
Today I've got my stock DS2072 scope and hooked it up to a home build pulse generator which surprised me!
It is bone stock and havent't entered any license codes yet. Having about 2050 trail minutes left, it clearly shows a much higher bandwidth than the claimed 70 MHz. I've measured a risetime of 1.646ns (50 Ohm terminated) which equates to a bandwidth of roughly 210 MHz. It looks like the higher bandwidth 'option' is also active during the trail period?
You need to extend the pulse at its high level. The scope is doing a 10 to 90 measurement on a pulse that no doubt doesn't reach its proper peak.

Is the option screen showing you a 200MHz option ?
Is the system info screen saying it is a DS2072 ?
When I got mine DS2072 there was a standard 4 ns rise time, so I guess Rigol is now giving it away on their 70MHz models, or they made a stupid mistake by configuring it wrongly.
Another possibility is that your scope has been altered by the dealer/seller.

You can clearly see from the picture that the rise time is about 1.5 to max 2 ns. so what the scope indicates is probably OK

The option screen shows a regular 2072 and I have checked the rise time is calculated correctly at the 10% and 90% limits as shown by the cursors set to Auto.
I doubt the dealer has tweaked anything, initially the DS2072 was sold out and it took another three weeks for mine to arrive.

Go watch some Rev blog videos where Dave and others had to extend the pulse width to get a full pulse so that scope will measure / calculate the right rise time ... And hence lead you to a closer analog bandwidth setting.

I agree with you that the pulser would benefit from a pulse lenght that is longer (replace the capacitor with a open 50 ohms coax of 30 cm), but in this case the pictures from nack leave no room for mis-interpertation, and the measurement is correct !

I'd say its measuring 10 to 90% of the pulse it saw, and with a bandwidth most likely closer to 100MHz.
It didn't see all the pulse and as its got a smaller pulse and hence as its a delta. It comes back with a shorter time. Not the real rise time of what the pulse should be to gauge what the bandwidth is.

BTW, I'm not knocking the scope. I have one :-)
But do that plotting points not vectors turn off sin x / x and it shows a different picture.

Just got notified that my 2072 will be shipped on 8/30 versus 9/24... yay. About the only way I can offer payback for the hack is to provide info. Is anyone looking for info on these units? HW versions, FW versions ...?

When I am thinking about it, you are completely correct. I have added a little capacitance to the main cap to stretch the pulse a little. The risetime is now 2.9ns which equates to about 120 MHz. Much more in line with expectations for a stock 2072.

Of course a real 200 ~ 225 MHz is only a key gen away :-)

I have come a little further with my DB832. Here ist the JTAG pinout. I have already copied a part of the RAM. Exactly the same ECC parameters as the DS series! Can someone please send me a working serial / license combination? AAAB and DSAB not work...

Hmm, curious. In Dave's tear down of the DP832, the sticker inside said DP832A. Yours seems to show DP800....

Ahhhh... I see.
They must have some that say DP832A and some that say DP800 inside then... </end conspiracy theory>.
