for P models not, but for B/BMV/MSO models, see the first page, there are links to schematics. I would say best reference is hw1007 schematic (is the newest i've made).
also the B version may still have the spot for the logic analyzer inside. The P does not.. I might have tried to find a B version if I would have known that and had the extra money.
Is it possible to buy the LA board separately?
or build your own maybe?
Thanks for all that work.
Also you send a bug report to Hantek about duration trigger. This makes me wonder if there exists an 'official' bug list
Did you notice the 'Black Hole' of about 2.5 us near the center of the LA traces when at 800ns /div?
I just got my DSO5072P in the mail so if there's anything you'd like me to check out, BMOW, feel free to ask.

Lucky you! I don't think there's anything specific I need tested, but general impressions would be good. I just can't seem to decide between the DS5072P or the DS5062B (or something fancier like the Rigol DS1074z). The -72P has the advantage of being cheaper and not needing any kind of front end resistor tweaking, but the -62B has the advantage of long memory. I'm thinking that for debugging microcontroller stuff I might really benefit from the long memory, but not sure if it's really worth it.
I should probably just shut up and buy something already. :-)

well not only that, but the B possibly has the LA spot as well, so you could turn it into a MSO as well

hmm, no, i don't see it. Try to make a screenshot of that, not that your display is broken :\
Pic_45_1.gif at 2us/div shows a set of equally spaced pulses on traces D0-D7, D0 is also present on analog CH1.
Pic_45_2.gif at 800ns/div shows the same, but now a 'hole' appears near the center of the LA traces of about 2.5us, pulses on D7 and D0 are missing.
Pic_45_3.gif after a little Horizontal Shifting the pulse on D0 becomes visible 'out of the hole'. The 'hole' is at about 0.2 div right of center.

I wasn't even considering the MSO, but that's the kind of data-altering firmware bug that should make anyone think twice about buying Hantek. It's definitely got me worried. I can live with occasional lockups or other little firmware glitches, but not something like this.
It's not only that the pulse on D0 disappears, but the timing of all the following pulses is completely wrong!
On the other hand, the logic analyzer is definitely an afterthought (and we DO only have one example of this occurring) so I don't think we're likely to have such issues with the in-much-wider-use DSO section, but still...
On an unrelated note I used my Hantek to debug some bits of my oneTesla ( http://onetesla.com/ ) musical DRSSTC earlier today and it worked swimmingly.
With the tool from Peter http://peter.dreisiebner.at/dso-usb-tool/ to get virtual shell ?
What is the current firmware release for the DSO5102B? Mine is 2.06.3(130814.0). Hardware version is: 10070x555583e8.
Has Hantek now leaped to firmware version 3.0 or is that just for new models?

you are on the latest FW for your model. Regards the 3.0 FW, afaik for now it is only for new models.
Even if a version 3.0 firmware is released for older DSO5102s like mine, my fear is that it would include some form of protection against the BW upgrade many have been using, and equally as bad...no way to flash firmware back to Level 2.0.
