New Hantek DSO2X1X models?

[Russ3000]

Seems fine 

Edit: New software update available: 2022.10.28

They tried to fix a bug with connecting 50 Ω in the generator, but they made new bugs. Now the voltage when switching the load of the generator abruptly decreases by 2 times.
It is necessary and sufficient that when the load is switched to 50 Ω, the generator voltage indicator shows 2 times less, and when the generator load is switched to 1MΩ, it shows the real voltage. Everything.

I bought a new DSO2D15 last week. It had firmware 3204, unreliable USB connections and couldn't decode/trigger on UART. I backed up everything, installed firmware 3205, applied USB Fix, and restored Hardware info (from the backup). EVERYTHING I tried works now, including USB and UART trigger/decode. Despite all the bad things said, I love this scope! THANKS DAVIDALFA!!!!

It's a Bingo, congratulations 

[DavidAlfa]

Congratulations!
You're the first user reading the FAQ/thread, following the available instructions and finally making its first message without asking the same stuff again! 

Yeah, not an engineering marvel, but if you got it cheap it's pretty decent.
What did you pay for it? Looked few days ago, prices had doubled since 2021.
Definitely not buying it for $350!!

$260 from an Amazon seller, including the DSO2D15 scope, two probes with various probe adapters and clips and cables and connectors. When I documented my experiences with the USB and UART decoding problems, and asked for a FW update, they forwarded me a zip archive of a "platform-tools_fpga_3205" folder layout with the FW3205 images and very terse installation instructions. I relied much on your FAQ for fuller context. Their instructions only covered the FW update; the scope's front USB was almost unusable after that, and the hardware info was missing from the System Info screen. But your advice and .upk files all worked like a charm to round out the final result of everything working nicely. (THANKS THANKS THANKS)

Here's what their cmds.bat looked like:

  sunxi-fel uboot images/uboot_fb.bin
  fastboot flash boot images/uboot-with-spl-spinand.bin
  fastboot flash logo images/logo3.bin
  fastboot flash dtb images/suniv-f1c100s-licheepi-nano.dtb
  fastboot flash kernel images/uImage

  fastboot flash rootfssize images/rootfs.size
  rem fastboot flash rootfs images/rootfs.ubifs
  fastboot -S 20M flash rootfsa images/rootfs.ubifsaa
  fastboot -S 20M flash rootfsb images/rootfs.ubifsab
 
  fastboot flash cache images/cache.ubifs
  fastboot flash data images/data.ubifs
  fastboot reboot

If it would be helpful, I can send you a link to a copy of the folder they sent me, particularly the images sub-folder that contains all the binaries used in cmds.bat. Cheers!

Currently uploading to the Hantek drive
I ran out of space, I'm migrating everything to a new account, links in the FAQ are currently broken, wait about 20 minutes.

So in this update Hantek is no longer flashing rootfs.ubifs.
Turns out it's unnecessary (Blank filesystem?), can be skipped and directly proceed with flashing rootfs.ubifsaa and rootfs.ubifsab.
All the .ubi files are unused, seems to be the original ubi images before they were ubinized into the .ubifs files.
And sure, I tested this in the worst-case scenario, zeroing the whole flash, then restoring with this, worked perfectly.

After cleaning all the useless stuff the size dropped dramatically!
So much that I made a Platform-tools package with all versions fitting in just 47MB.
Added a simple choice script, simplified the driver installation into running "install_driver.bat", Zadig or Phoenix_msi are no longer required.

DON'T BUY HANTEK!

What buy?

I'm sorry, but I didn't get the link via pm. What is pm? - personal message? No link in My Messages. Could you please send the link once more.
Thanks

[DavidAlfa]

Yes PM means that.
I uploaded it here. I will delete it in a few days.

gaahh,  I thought I had this working under Windows 11 22H2,  but in my messing about it seems I had removed the 22H2  so it works on the previous, (21H2?)  but not 22H2.

tested with fresh installs and several versions inc Win 10 22H2 (works)  but does not in Win 11 22H2.

Also tried  the latest IVI shared components from ivifoundation.org   which work fine in all versions Except Win 11 22H2

If anyone has got it working then please let me know how.

How measure wfm/s without ext trig out?

[DavidAlfa]

No idea.
Anyone knows how to view exported waves exported in native LWF format? Or huge CSV files?
I mean, no simple csv to picture converters, but interactive viewers that let you move, zoom in/out.

[DavidAlfa]

Yeah, I knew it. But uses Python. Which I hate for several reasons.
It's nice for some scripts, but people use it for large workloads.
Any change to the window, movement, takes 5 seconds. Only uses 15% of the cpu...
Slow as hell and almost unusable controls. But lots of potential if done right.

In the end I exported to csv and used Flow CSV Viewer.
Works great, it's extremely fast and has a very handy interface.

Just to show a real screen shot of DSO2D15 UART decode, at 115200 baud, here it is. It was a stream of ASCII characters "ABCD...", using the UART "Spec data" trigger of 43x (the letter "C").

The UART decoder seemed to cause lockups when used with misconfigured triggers. I found it helpful to keep UART decode turned off until I had my trigger working right. The UART decoder was reasonably stable when used with the UART trigger. I was able to configure an Interval Trigger to pick up the start of my uart stream, and that worked well.

[DavidAlfa]

If you're going to work a lot with the uart decoder, consider trying the patcher to get ASCII output instead hex.

Friends, does anyone know the purpose of the TR line of the power supply?
There is a positive experience of powering the digital part of the device from the power bank. The analog part can be powered from an isolated converter DC - DC 5 -> 2x9 volts, 0.13A, for example REC3-0509DRW, while my analog part is powered by a transformer.

[tautech]

Friends, does anyone know the purpose of the TR line of the power supply?

Probably Trigger Reference to mains, what most brands call a Line Trigger.

It's precisely that, it shouldn't be necessary if not using line trigger.

But a user has reported problems in the boot procedure when this signal is absent, but I tried shorting it to GND (no problems, there are high-value resistors upstream) and the scope booted without problems.

As you can see in the schematics, the TR signal is not only connected to the triggering circuitry but also to the FPGA, as you can see here and here. That may explain cristy's problems but, as I said, I didn't see anything strange in my case.

In the worst case, that signal can be recreated by a 50-60 Hz oscillator (555 or similar) for battery operation but I see in your experiment you didn't need it to boot the scope
