New Hantek DSO2X1X models?

[DavidAlfa]

Update to fw3202. Check the FAQ.

[bianchifan]

At least I ordered one last week at Aliexpress. The order was confirmed first, two days later I received a messageto confirm the new EU VAT handling. Today I got the message that the item is out of stock and and will not be produced by Hantek before end of September, I was pleased to cancel the order.

[Piton]

Apparently, we won't see the new firmware before September either.

My DSO2D10 arrived today.    Came with an unbranded 150MHz probe.    I suppose they know we are all going to hack them.

From the tape, I could tell the box had been opened twice.  I was a bit concerned but the scope looks to be entirely untouched.   My guess it was opened for export customs in China and then again by UK customs.   - There were delays at both.

I've only had time for a quick power on check.  So far it works as expected.

Shipped with:

Software 1.0.1.1.0  (20210416.00)
Hardware 000.000.000.000.000. ..... .001
Firmware  3200


I'll be making backups before doing anything else.

[Spenoza]

On my oscilloscope hardware all zeros:
Hardware 000.000.000.000.000. ..... .000
At the same time, all other data is normal,
the firmware was 20210416, the hardware version is 3200, the serial number is correct.
What is the reason for this. Who knows?

[DavidAlfa]

Your's must be a DSO2C1x model, .000 is no wave gen, .001 is with wave gen

[Spenoza]

Yes. and there is. I have already changed the model to 2D15 according to your recommendations. And how can I change this number? Suddenly, in further software updates, the manufacturer will make a check on it.

[DavidAlfa]

There's no need todo so. Any of these options (Model or HW) matching the wage gen model will enable it.
So you can enable it by changing hw to .001, setting model to 2Dxx, or both.

If you want to change it so badly, use the script from Drive  and run it with the script launcher package.
Check the FAQ.

[Spenoza]

Understood. Thanks.

Hi all, new soon-to-be owner of a Hantek DSO2C10 here. Active in other hacking communities but never on oscilloscopes.
I have CAREFULLY read all the recommended posts here and on the continuation thread. I'm posting a question here simply because this one seems more active.

Questions:
 1. The latest Hantek firmware on their site is dated 20/4/2021, but user @DavidAlfa lists firmware versions up to 14/7/2021 on his Google Drive repository. Are these ones similar to that mentioned below? Or are these simply versions found in the wild and submitted by users?

These will overwrite you FW version, so don't apply unless you run the same FW version!

- 20201221 -> Sets FW3000
- 20210510 -> Sets FW3202
- 20210601 -> Sets FW310

2. Are there any changelogs for any of the updates?
3. I gather that there is some user-made firmware out there. The Google drive repo is not helpful here. The continuation thread has a section promising note "List here the firmware updates available and recommendations." but has no content yet. Is there such a list?

Thank you for any helpful advice.

Hi guys.

So today I received my 2C10 and came with the missing components populated:





Board:



Have anyone who has changed his C10/C15 noticed misbehavior? or anyone have tested if the 150MHz bw it's really there?

[HappySundays]

With DSO2D15 written on the PCBA then you'd hope so! I hope mine arrives with the same.

I think that all 4 models share the same board it just hardware arrangement differences, but I don't know if there's a hardware difference to achieve the 150MHz bw.

It be  really nice I the C10 can be converted to the D15 

Still, it's a really nice scope for the price.

Hope that your scope also comes with the goodies 

[Algoma]

I see the didn't scratch off the brand on that DAC. Curious they would use such a quality brand part as a Burr-Brown DAC (if it's genuine), especially considering the price point of these scopes. I think Hantek was aiming for a step higher class with these scopes (Undercut the $400 market) , but software and front end held them back so far.

Hi.
I have Model DSO2D15

Software 1.0.1.1.0 (20210416.00)
Equipment 000.000.000.000.000.000.000.001
Firmware 3000
Unstable sync
Applied dso3kb_20210714.
Hanging issues disappeared, but not stable signal sync in Falling mode.
Do I need to apply dso3kb_20210630_auto_update_fpga or should I not?

[DavidAlfa]

There are no changelogs. Let me explain:
User A complains to hantek for specific issue. Hantek sends custom update to the user A.
The update migh or might not solve anything. There's no changelog. Just "Try this" from Hantek.

Then user A sends this update to me and I add it to the list.

All I can say is: Once you made the backup, you can mess with it as much as you want, these things are undestructible.
In the worst case you'll need to recover using platform-tools and restoring your backup.

[Piton]

I tested my 2C10 before hacking. After hacking, I did not notice the difference.

This surely gives us confidence... 

Well, we get what we pay for.

1. See DavidAlfa's answer above.
2. No!
3. No, there is basically no list of recommended firmware updates because right now the situation regarding updates is as confusing as it could get. My personal recommendation at this stage and until Hantek really gets its act together, is to keep whatever firmware you get with your DSO. Or if you want to try various updates, you can follow DavidAlfa's guidelines to backup and restore the firmware you got with your scope, but that might just end up being a huge waste of time with little benefit.

Until Hantek publishes a new firmware update and various DSO2X1X owners test it and declare it good to go, I will continue to recommend avoiding any updates. Enjoy your DSO once you receive it and don't worry about updating it for now!

[Algoma]

Goes to show the issues Hantek is fighting with appear to remains the CPU bound software trying to keep up with the capture engine's timing and status.

I can only imagine where the capture memory buffer is stored. While the GOWIN FPGA can have RAM options, the CPU has plenty more than 8MB available for Buffer Space. Either case there is definitely some improvements to be made between capture memory and display memory timing. Zooming and panning too much seemed to eventually cause display issues, like it lost track of some of the original captured data. This may be have been resolved in more current updates.

[DavidAlfa]

The CPU is connected to the fpga via spi, so that's a huge bottleneck.
You're limited to the fpga dram memory at normal sampling rates, while only the sram can follow the fastest rates.
I don't think it's a bad scope. It's really good for the money.
It's the software what needs some fixes, mainly in the decoders and trigger detection.
Otherwise it has proven to be very useful.

Thanks for taking the time to answer my questions. I'd still like to try to do the DSO2C10 -> DFSO2D15 conversion (assuming H/W fitted to PCBA) and I think there is just enough info posted to do that update. I'll do my best to process the instructions and come back if I run into trouble.

[.rpv]

So, for some reason, I was thinking that in order to do the conversion you'll have to get/install a few utils and edit a few files and it turns out that you only need to create a single file with 2 lines 

I did it and the fungen works now:












Test setup it's a bnc-bnc home-made using RG316 wire, length: ~50cm

Love the scope but the fungen seems pretty basic.

Many thanks to all people involved on the hacks/discovery.

The function generator in the DSO2X1X scopes is indeed pretty basic and limited, as expected for a $20 option (or free in your case) on a $200 DSO. If you really need a function generator for lab work, a standalone, separate function generator is recommended, and you can get a pretty good one for less than $100 these days. The same applies for the protocol decoders on the DSO2X1X scopes: they are there, but even a $5 USB logic analyzer + sigrok free software do a much, much better job.

Enjoy your new DSO!

current general thoughts on these models? i need a second scope but i dont want to spend as much as my main bench one at the other office. if you have to buy again would you choose this one again? if not what would you look to? i have not bought a scope in a while even my other one is a bit outdated but its built like a tank. this is for a second setup for quick use normally a few times a week. id spend up to maybe 350$ or so of course less is better IF it performs well enough.
