I have the same problem as masta_k74 and naelolaiz with the signal jumping around above 40kpts.
I got mine from Bangood. SW0726, FW3202.
Did you contact Hantek Aliexpress shop or the official Hantek support on their website?
Please send me the email address, I'd like to drop them a message too.
If this is a hardware related issue, I don't think Hantek can solve it.
I'm thinking about applying for refund.

I am in contact with the Hantek Official Store via Aliexpress and sometimes by email.
Here is a post of mine about this problem on the Hantek Forum. Please add your problems to this post so that people there realise that it is clearly a bigger problem.

I got mine (2D15) from Bangood too. I am currently waiting for the technical support to tell me something after sending them videos showing the issue. Sometimes it doesn´t happen on power on for a while (at most a minute?), but then it is constant. 4K and 40K works good, more than that is garbage.
I would also like to know if it is a hardware or software issue.

Quite a few pics show flux residue around the FPGA or ADC having been reworked at manufacture. Both are QFP144 with quite a wide parrallel data interface, thats alot of pins to get right. One bad joint could certainly show as a repeating n'th bit error in sampled data.

But with these cases, I get the feeling Hantek is still fighting with timing issues between various parts. It takes careful timing to keep that CPU, FPGA and ADC working on the same task. One missed clock cycle and bits can be read out of sequence.

I think so too. Otherwise, the support staff would have told you to send the device in long ago. They clearly suspect a software problem. Otherwise they wouldn't have sent me an e-mail with new firmware straight away. Of course, it could also be that they are trying to stall for time in order to avoid a refund.

I was able to reproduce the same issue on mine 2D15 with FW 20211221, it was not happening before, but while i play with generator, memory depth and horizontal scale i get the screen attached below, with no probes on the scope. Than while i try to reproduce it again the scope freeze and it stay without beams after restart from power on switch few times. Only beeps and no reaction, so i become nervous and press "Auto set", "Default setup" and Power cycle. This help me to get rid of this deeeep freeze, so i make "Default" again and update it to 20213112. Honestly i stop to play after that and now i am also waiting for more user responses or new version. So i also start to think that there is some timing issue and it is FW related problem.

Please upload the .upk that Hantek has sent to you to David Alfa's GDrive so that it is available to everyone, since at the moment on the official Hantek website only version 20211230 is available for download.

In my case both channels 1 and 2, when they are set to GND coupling and set to 50mV/div, both have an offset of between -26 ...- 28mV (the trace line is below the zero line). And this has been happening since the factory version 20210416.00 on my oscilloscope.

With more cases timming seems to be the problem.

But still, I don't get why this problem it's not present on more scopes, for what I recall from this thread, aren't that many hardware revisions, just 2 PCB revisions for the digital board and 2 for the analog board, isn't?

Maybe the scopes with problems could have a different PCB/hardware revision?.

Go to this link and read the readme file.

how do I load the SW dso3kb_20220105.upk on David Alfa GDrive?

Go to this link:

You can create in the folder "Writable (anyone can drop their files here)" any folder (with right mouse click) and load your files into this folder (with right mouse click).

Hi vistorik!
I think I've managed to post it, it's in the folder
"dso3kb_20220105.upk Solves problem of displacement of lines in GND coupling"
See if it solves the problem.
From: Fernando Santos "CT1EFF / PY2ZFC / PX2Q3525"

I've downloaded the dso3kb_20220105.upk and installed it on my device. There are many changes in the /dso/app/phoenix compared to the dso3kb_20211230.upk.
When I set CH1/CH2 in GND mode only the CH2 line goes just a little bit down. The same was with the dso3kb_20211230.

popy5 · « **Reply #861 on:** January 06, 2022, 03:33:39 pm »

Hi Fernando, in my case I have applied the new update and the problem has been partially solved: the traces of both channels are now centered on the zero line when I select GND coupling, except in the 2mV/div scale in which I keep observing an offset of 300 to 400uV.

But on the other hand (always without the probes connected) I now observe a slight offset of about +400uV in the AC and DC coupling modes that I did not have before (but only on the 2mV/div scale).

I have reinstalled the previous version (20211231) and recalibrated again and I no longer have the offset values that I always had. The offsets of version 20220105 are kept, which means that the calibration values have not been rewritten (?).

Maxie · « **Reply #862 on:** January 06, 2022, 05:28:10 pm »

I have also posted on the Hantek forum describing my problem with the jumping signal spikes.

I was able to reproduce the same issue on mine 2D15 with FW 20211221...

You should also post there, so we can get an answer sooner.
At least to understand if it is HW or SW related.

Calibration of internal AWG DSO2X1X ( DAC902E )
Important to notice that the offset value should be measured when in SINE mode , this
mode gives us 100uV step resolution for most accurate measurment for offset calculation. DC steps are like ~1,3 mV...

I am sorry, where (whether the device should be opened?) how (AC or DC) and in what way (multimeter?) do you suppose to make these measurements?

The gnd coupling fix is great news!

Victor1964 · « **Reply #865 on:** January 06, 2022, 11:49:50 pm »

Test version SW dso3kb_20220105.upk in my DSO2D15 removed the offset in GND mode. Synchronization has become more stable! From the internal generator, it works normally, starting from 0.1Hz. Earlier at low frequencies (1Hz -20Hz) it was sometimes not very stable.

DavidAlfa · « **Reply #866 on:** January 07, 2022, 03:08:33 pm »

People uploading random files my Drive, please attach some description.
Ex. 20220105 was nice "Fixes gnd coupling", perfect.
But I have a new file called dso3kb_20210726_full that I have no idea what it is.

Tried the update, gnd issue was still there.
Ran a new calibration, it almost went away, still has a minimal drift (1/2 of a sub-division), but it's ok, much muh better than before.

I have problem with DSO2D10. The oscilloscope freeze after zooming horizontal domain with displayed cursors. I tray following steps many times with same result.

1. Connect signal on Chanel 1
2. Set the cursors A and B in mode Track
3. Zoom the horizontal axis by clicking Sec/Div button
4. Change the time(horizontal) range, after zoom the cursors are not in window (out of display on zoomed part)
5. Click to clicking Sec/Div button, try to exit
6. The device doesn't response, display is frozen

I have DSO2D10 have with SW 20220105

Do you also have this problem or is it only my own problem?

Edited: The cursor type should be in mode Track, cursor in mode Manual works correctly

I confirm that on my device (DSO2D15 with firm 3202 and soft 20220105) this problem also occurs, but only when I set the cursor mode to Track. With the Cursor Mode in manual this problem does not appear. Also, if you don't try to change the zoom level, it doesn't crash.

In addition, the same problem is also reproduced if instead of trying to exit the zoom mode (after having modified it before) the Auto Set button is pressed.

Therefore it seems that the problem, at least in my case, appears only when the Cursor mode is set to track and you modify the zoom level before.

I also confirm the bug, tried on a 2C10 converted to a 2D15 (FW3200, SW20211230) it freezes when you try to exit the zoom window.

petr_cz · « **Reply #872 on:** January 18, 2022, 07:28:26 am »

Thanks to all to confirm the bug in SW. I send the e-mail to Hantek and we will see if the bug will be fixed in next version.

New firmware online:

I can't check because I don't have a Hantek oscilloscope, but I follow this topic regularly

Thank you for your feedback, this issue will change in the next firmware update.

Hopefully the fix is in this release.
