New Hantek DSO2X1X models?

[tttonyyy]

That's odd.  The slope doesn't look linear, as though there is some form of AC decoupling.  If you slow down the AWG is the slope more pronounced?

tttonyyy,
Re paying for the hantek, yes i did pay with paypal and thanks for the reminder about my rights.

However Banggood have a Get Out Of Jail Free clause.

Have you contacted Hantek about this problem, Yes
Did you follow their advice, Yes i uploaded the new firmware.
Sorry will don't accept returns of modified products. :-(

Follow their advice and get back to us. :-(

This is the Kobayashi Maru scenario, anyone know James T Kirk's number :-)

I think the way the return request is going I shall be out of time on Midnight Friday.
Not too worried, either ebay it, or await next firmware from Hantek which is few weeks overdue.
Maybe they are feeling the flak from these threads and having a do or die last push.
Has anyone checked the job adds for programmers at Hantek :-)

BTW when reporting new DSO2xxx features would it be worth noting the firmware release number/date?
all the best imk

It's not the AWG, anything you throw there with too high level and 20mV/div setting(1x) or less, makes it!
Will flash it again and ensure it's not a software issue, but...

My Hintek DSO2D15 is OK

My Hintek DSO2D15 is OK

What firmware version are you on please?

[Sergey_Malyshev]

I have a question?
Unintentionally installing the update dso3kb_20210510. On the FW (3000) software. The oscilloscope stopped working as it should !!! How can I become a licensed owner of this device? (DSO2D15)

DSO2000 Firmware
2021-04-20

From Hantek site download firmware http://www.hantek.com/products/detail/17182 20210420
Or David Alpha gdrive https://drive.google.com/drive/folders/1iw9BOnvxNOd0f_2uvGwGSHmnjP4TrG4f
Has most/all the previous versions, apparently 20210304 is fairly reliable although I have crashed it and had Mem Depth 8M issues.
I think all are awaiting the next exciting chapter in the saga known as Hantek DSO02xxx firmware releases :-)  enjoy, it is marginally better that toothache!

Inmcorrect, that update doesn't change Fw version!

I will delete that version as it only changes the fpga firmware, nothing else!
Check my GDrive folder, go to Mods/FW changer, download and run FW3000 update. Done!

These important details shuld be in the first post, actually the info is spreaded all over 20 pages (and rising), making it hard to find.
However, thread starter seem to have gone long time ago (Last login: December 30, 2020), making most important post completely useless.
People willl keep flashing wrong versions because of this.

Moderators: Can we take control of the first post to use it as an index / summary?

@DavidAlfa,

That is the best advice to date.

As an obvious newbie on these topics I am in awe at the depth of knowledge possessed by some of you.

As a newbie it is actually confusing to draw any sort of conclusion from the 20 odd pages of comments put forward so far.

A summary of what has been learned so far from you guys will be greatly appreciated. For example the implication of the various firmwares 3000, 3100....3202 on the scope and which one to choose for a particular model!!!

Thanks for ALL your input.

Regards

The problem with the generator remained unresolved.
FW(3000).dso3kb_20210416.(DSO2D15)

I would suggest locking this thread and creating a new one with a first post that clearly explains the firmware update process, but still references this "old thread" for those who want the complete details, and also references the "hacking" thread for those who want to explore their Hantek DSO2X1X.

And perhaps in the new thread we can move on to comments about using these DSOs instead of bitching and whining about them (including by people who don't actually own one)?

EDIT: done creating the new thread, and I have reserved and will curate the first five posts with essential information and facts. The new thread is here: https://www.eevblog.com/forum/testgear/hantek-dso2x1x-firmware-updates-and-best-use-practices/

[tv84]

The sooner you create the thread, the sooner people move there.

Regarding the "bitching and whining", it will continue to happen on BOTH threads.  It's a feature.

[Gerasim]

I have also written here more than once about the problem with the generator.  Rollback to the previous firmware does not help.  But apparently few people are interested in this))

[Sergey_Malyshev]

Let them work! Let's not get distracted by trifles. I hope they heard us.

[Piton]

 Sergey_Malyshev, try long pressing the "Default Settings" button, there are options for a generator and maybe a calibration. I fixed this problem by soldering the memory and only then did I find this feature. But, as it turned out, it does not work for everyone.

[DavidAlfa]

It seems to work after you entered Utility menu first. The older sw versions have more options.

[Piton]

I also thought that in later versions they either removed it, or hid it somewhere. I have a very early version.

[Gerasim]

This menu also opens for me.  But unfortunately, the generator calibration does not work and gives errors

[Piton]

So you need to restore your version. I didn’t have any errors on the error generator, I only had one of those points, but this was after recovery.

[Gerasim]

I originally had version 3000. The generator worked without errors. And there was only one calibration item in the menu. After installing versions 3101 and 3102, two calibration items appeared in the menu and a generator error appeared. When I installed my native 3000 version back, the problem did not disappear, but these two calibration items remained in the menu. Apparently the new firmware 3102 registered something in the flash and rollback to the old firmware does not completely erase the 3102 firmware data from the memory. So which version do you say I should still rollback to?

[Gerasim]

If there is no way to format the flash via USB without unsoldering it from the board in order to write the firmware to a clean flash, then you will have to order a new flash on Ali and try to upload the image to it.

[DavidAlfa]

I found few things:
- The fpga file from platform tools fw3000  is not the same as my factory fw3000 backup.
- Generator amplitude is fixed after restoring my files "/cache/cali.dat" and "/cache/dds_calbration.dat"
- Made a custom update package that replaces all /dso and /cache files with my factory ones. Worked.

Gerasim, try the attached update and tell if it makes any difference.

See the hacking thread. DavidAlfa and I are working on two different solutions to read/write/backup/restore/modify the SPI NAND flash. DavidAlfa is writing a low-level program that reads and writes the SPI NAND flash through FEL. I am working on a small Linux distribution that can be loaded through FEL and uses the Linux kernel SPI NAND driver.

[DavidAlfa]

David is actually waiting for the ram linux method!
