DavidAlfa and Gerasim you guys rock!! I tried with another computer and it worked now. It was either driver not installed correctly or because of USB 3.0 on my laptop (I tried 2.0 now).

To my surprise, my DSO2C10 has all the components for the function generator and it works like a charm. What a steal for $185!!!

Now that I feel safe with tinkering a bit more, it's time for OC.
Thx again

I increased Vcore slightly over specifications.
Nominal is 1.1V, max 1.2V, I got 1.25.
I'm currently testing and modifying the overclocking script, because I had to use the second PLL_K multiplier to go over 768MHz.
But it seems stable at 912MHz

And factory default is 408MHz, not 384, I had missed that multiplier = Val+1 (default value16, but effectively 17)

The overclock interests me, but i am little concerned about temperature rise.
Did you happen to do a pre and post overclock temperature check?

I already said a few times. It barely gets warm.
The worst that can happen woudl be a system crash, requiring reboot.
Don't try it yet,.I'm updating the overclocking script.

Ok David
Thanks for info, i'll await an update.

And the Voltage/Frequency table I found in my tests:

About 70MHz gain per 50mV step. Except the weird spot at 1.3V.

I discovered a strange thing - I have 2 capacitors soldered to the legs of an unnamed chip. I have not seen this in other photos of this board. Does anyone have this? I wonder what the Chinese wanted to adjust in my scope?

Algoma · « **Reply #532 on:** June 30, 2021, 04:17:18 pm »

Those are across each of the ADC's differential input pairs from the front end. I have these on my DSO2D15 from January. They're noted in the photos I posted back on page 3 or so. Some units have them.. the flux residue indicates they're installed by hand after manufacture.

DavidAlfa · « **Reply #533 on:** June 30, 2021, 04:19:06 pm »

Sure, probably a later revision of the board, to avoid noise or enhance signal integrity.
https://www.eevblog.com/forum/testgear/new-hantek-dso2x1x-models/msg3434052/#msg3434052
Mine also does have them.

I updated the overclocking script, now it allows to fully customize PLL N/K/M parameters.
There's a new test mode that loads the script from the usb drive, so you can try anything without fear, if there's no drive, there's no overclock.
When you find a stable overlock, then run the permanent installer, and it will load automatically from the internal memory.

I also made a fix for the platform-tools 20210517 version. The usb problem is purely caused by the phoenix app.
Replacing it with the previous version (Phoenix-20210416) completely fixes the issue. You can also run the 20210416 update.

I used it in my FW3000 scope, worked perfectly
- Install platform tools 20210517. Don't worry about the usb issue, it will start working when you hit Utility/Update few times.
- Install usb fix (Phoenix-20210416 mod package)
- Install Backup-CNxxxxxxxxxx.upk (Read above).

I also modified backup builder. Now generates two files:
- dso3kb_CNxxx.upk: Restores Model, Serial, HW, FW, Generator calibration, but skips dso, preserving the existing dso software.
- dso3kb_CNxxx_FULL.upk: Restores Model, Serial, HW, FW, Generator calibration and dso, overwriting the existing dso software, almost like restoring the original system.

My DSO2D15 must be a revised later hardware version because it does not have the capacitors soldered on the pins of the chip U38 (they will now probably be C38 and C49), and the capacitors C439 and C440 are now in a different position relative to U38.

DavidAlfa · « **Reply #535 on:** July 02, 2021, 08:12:47 am »

Seems so. Check the pcb version, it comes with the date.

popy5 · « **Reply #536 on:** July 02, 2021, 11:28:14 am »

My main pcb: DSO2D15_V1.7 2021.1.14
Secondary pcb (knobs/leds/...): KB3000C V0.5, probably manufactured in week 47 of the year 2020.

Fw3200 ?

popy5 · « **Reply #538 on:** July 02, 2021, 11:58:18 am »

Yes, with software version 1.0.1.1.0 (20210416.00)

DavidAlfa · « **Reply #539 on:** July 02, 2021, 03:36:11 pm »

I suspected it, but now it's clear that fw3200 is for a different hardware than fw3000

Gerasim · « **Reply #540 on:** July 02, 2021, 04:49:50 pm »

Apparently, this is why Hantec has not been releasing official firmware for so long. He's now confused to release a universal firmware that fits both fw3000 and fw3202

DavidAlfa · « **Reply #541 on:** July 02, 2021, 07:42:32 pm »

I don't think so.
The firmware updates usually update the dso app but not the libraries(which interface the hardware).
The calls will probably be the same. You can run any software version, as long as the FW (fpga programming) is correct.
Confused? Maybe you meant incompetent.
I'm pretty sure that most issues could be fixed in some weeks with a proper team of experienced people.
The fact that they started selling it with a software that crashed every 2 minutes says a lot about them.
If the average user knows these issues, what will hantek people know!
Maybe it was targeted to a more expensive market, but they screwed up the design and had to get rid of them by selling at low lost?

Piton · « **Reply #542 on:** July 04, 2021, 09:26:30 am »

DavidAlfa, i tried to install yours Lock-ap fix. When freezing, the monitor readings are restored, there is a reaction to the input signal, but everything else is blocked, you still need to reboot. Is that how it should be?

DavidAlfa · « **Reply #543 on:** July 04, 2021, 09:02:24 pm »

Yes, I know it happened, it was caused by another process locking the keyboard (dbus-daemon).
I thought I had updated the file, but it seems I forgot. Updated now.
Download it and install again (No need to remove first) .

It looks like i'll be keeping this DSO2D10 for awhile, hence i have taken the back off to see what board versions it is; DSO2D15_V1.7 2021.1.14
So i am wondering what you think will be the best .upk version for it will be, plus with your crash detection reboot solution please?
imk

DavidAlfa · « **Reply #545 on:** July 05, 2021, 02:28:23 am »

I don't know? I don't have 20 hanteks at home

You can install any firmware without fear. First run backup builder and store the files.
Then you can try update. If any changes your fw, restore it by running the restore packages.
Crash solution? Did you see my Gdrive?

imk · « **Reply #546 on:** July 05, 2021, 08:14:33 am »

DavidAlfa
Ok i'll see which update is most stable, but am hopping hantek are going to release big fix all update soon.
I download dso3kb_install_lockup_monitor week or so ago, but i noticed in previous post you had new version so i'll get pull that down.
thanks again imk

popy5 · « **Reply #547 on:** July 05, 2021, 06:21:54 pm »

I sent to Hantek support the report of the errors that I detected up to date in my scope (see message https://www.eevblog.com/forum/testgear/new-hantek-dso2x1x-models/msg3591243/#msg3591243) and they have responded that as soon as the responsible engineer solves the first issue, they will contact me again. But for issues 2 and 3 they tell me they are resolved by the following firmware update file that they have sent me:

dso3kb_20210630_auto_update_fpga.upk

In case someone else might need it, I've already uploaded it to the public folder of DavidAlfa's GDrive ('popy5_dsodso3kb_20210630_auto_update_fpga' folder).

Please note that my DSO2D15 scope comes standard with the following software/hardware/firmware:

Software: 1.0.1.1.0 (20210416.00)
Hardware: 000.000.000.000.000.000.000.001
Firmware: 3200

Update: after updating the scope, my firmware version is now 3202.

Thanks for the dso3kb_20210630_auto_update_fpga I'll try it out later tonight or in morning.

DavidAlfa Question:
I have run the backup upk and installed the lockup monitor successfully, I'll try the overclock a little later this evening or tomorrow :-)
Question will lockup monitor and/or overclock util be overwritten by a Hantek provided upk update?
Or should i remove them first, do the new Hantek update then reinstall your utils?
imk

DavidAlfa · « **Reply #549 on:** July 05, 2021, 09:52:05 pm »

No. At least until now, Hantek updates only affect the dso folder and the fpga firmware.
