What I wonder, after watching Dave's teardown video, is can we add AWG signal generator to the DHO800's. It seems there is just one component missing that directly outputs on the back BNC.
Dave assumes its a buffer/driver, but it has a little bit unusual footprint and pin numbering... so I guess it is rather some generator module... But this could be answered only by a DHO9xxS owner Anyone?
If you don't have a generator that goes at least up to 300Mhz, then there is still a very steep square wave signal where you can approximately determine the bandwidth of your scope by its measured rise time.
However, the tests with the 804 showed that the bandwidth extension can be trusted.
I don't think I really need 250M (but more is always better)
Absence of BW 150 to 250 upgrade option (which disappeared in 1.01 update) confuses me, maybe it's only showing 250M in model and not working, if I understand correctly DHO800 still has 70 to 100 option listed in options tab.
With the upgrade to 250 MHz, you have now disabled the analog lowpass at the inputs which would previously suppress frequencies above 125 MHz. So you may see some aliasing -- IF you feed in signals which have such high-frequency components, e.g. fast square waves, AND you have more than two channels enabled.
Before the first firmware update, my DHO804 showed 70 to 100Mhz as an option, after the update ist was gone (and replaced by storage depth option).
Nevertheless, I was able to "activate" both, the bandwidth is now 100Mhz, measured even at 200Mhz.
Good news, will hope they won't remove this hack in next releases.

I'll maybe try to find signals with low rise time in some boards like esp32, arduino or similar.
I wonder wether going for a MSO5074 @ 1070€ and upgrading it to a MSO5324 @ 2569€ with 8 GSa/s (2 GSa/s with 4 channels) isn't the better deal, than spending 712€ on a DHO914 and upgrading it to a DHO914S @ 831€ (since the 250 MHz are not alias free due to 0,3125 GSa/s on the DHO900).
Well, the MSO5000 is not 12 bit

PS: To remove installed options use "adb\03 adb remove ALL options.bat" or the SCPI command from the manual.
adb is the Android Debugger. You can use it to hack around the 'scope, copy files to/from it, etc.
You can download it here: https://developer.android.com/tools/adb

If you were replying to me, I already have adb and have used it several times. My point was "adb\03" is not valid a valid command nor is "adb \03". Also remove is not a valid adb command.
Hello Everyone,
there is an adb-plugin for the Total Commander filemanager, which gives you easy access to the DHO filesystem.
Has anyone tested this? What exactly is "adb\03" and where is it supposed to work? It doesn't seem to work in a windows command prompt, in a shell nor in the SCPI command window. What is the \03 part?
"adb remove ALL options.bat" doesn't work as "remove" is not an adb command.
Some folders can read/write normally, others are mounted as ro and can only be read...
Maybe they can also be mounted r/w
