New Hantek DSO2X1X models?

[DavidAlfa]

Exactly! The first 3 options are true/false switches.

Code: [Select]

# Restore only, skip patching
RESTORE_ONLY=0

# Enable ASCII decoding
PATCH_UART=1

# Change plot colours
PATCH_COLOR=1

# These are the default colours
# Hex:     R   G   B
CH1_COL="\xFF\xFF\x00"
CH2_COL="\x00\xFF\x00"
FFT_COL="\xFF\x00\xFF"

Enabled uart ascii decoding without change plot colors option.
Thankyou davidAlfa

@carlonb: Where did you buy it from? I see banggood has good offer on the models right now

Hi keenox, I've buy here the 2c10

I saw Banggood but you need to add the shipping cost.

[Aldo22]

If you compare prices and have a little patience, you can get it really cheap.
I bought mine in november in a promotion for ~$130 including delivery here.
It's definitely worth that much.

Hi all,
I'm experimenting with some tools and tested the "dso_builder" by DavidAlfa used to extract or build the UPK files. This tool needs the installation of CYGWIN on windows to work, then I was able to use it.
Now I know that exist also a packet for Windows  "Windows UPK build-extract tools.rar" done by andry2pda but I can't find it, is there some one that can address me where i can download it?
Thanks in advance.

I attached a "Windows UPK build-extract tools.zip". andry2pda made bat-files, I testet. They work. But be very careful when using these bat-files, especially when building your own upk-files - you may end up with a non-functioning device. I advice using David's "dso_builder" tools, at least for building upk-files. I've added the english ReadMe file.

@ vistorik,
Thankyou for the file.
All this is only for couriosity and only see how these tools in general works, so I will be very careful using it.
Best regards

Hi all,

I've update my Hantek Wavefile Viewer. Originally it was Python only and used matplotlib which was admittedly very slow for large files but served to prove the point. I recently found some time to do a rewrite in C++ and instead of building a viewer it outputs the file as a VCD for GTKWave or Sigrok to use. I've successfully used it on 8M captures to analyse a WS2812B LED and also for I2C. Hopefully others will find it useful

[Aldo22]

I've uploaded a wave form with a 2Hz square wave to the AWG of the Hantek.
To my absolute astonishment, a stable square wave is generated at 50Mhz (2x25), which it can also display reasonably well.
I mean it's 50MHz!
Can I trust my eyes? 
(50Ohm Terminator, so should be 1.75Vpp -> 1.48 measured. Not too bad).

Who has the mathematical division function for two channels? Probably everyone has this mistake. Hantek has not yet released a fix. The math division function does not work.

Yes, that's one of the things that doesn't work, or I don't know how.
Strangely, it doesn't work with the PC software either, although it seems to calculate/display the math stuff independently of the scope.
Well, not such a serious bug for me.

[Aldo22]

@DavidAlfa: Is there an updated bug list for the latest software/firmware?
You once created one here:

The zoom window problem has been solved right?

»  Serious artifacts caused by undersampling, ex. a 10MHz signal shows garbage below 20us/div, you might not notice there's a signal there. 

The problem still exists. But I found out that it does show something under certain conditions.
- Acquire mode: PEAK
- Memory depth: 4k
- 2nd channel off
See attachment. No idea if this is helpful.

[DavidAlfa]

No. I barely use it...

[Aldo22]

The "Multifunctional Knob" really annoys me.
Is it worth the effort to replace it with a
PEC12R-4220F-S0024 Bourns, or does that not change much?
That would be this one, wouldn't it?

Can anyone who has done this share their experience?
Thank you!

[DavidAlfa]

Yes, it will improve a lot.

Thank you!
Do I understand you correctly that you have replaced all the encoders?
The big ones work fine for me and most of the smaller ones are acceptable.
Only V0 is really troublesome. It sometimes just changes direction depending on the rotation speed.
Unfortunately, I need it very often and for many turns, for the frequency of the AWG, FFT center, etc.
Sometimes I start the laptop just to make a setting via SCPI command. 

[DavidAlfa]

The encoders are cheap, it's the shipping what bulks the costs.
V0 was unusable, trigger level did some woes.... I didn't want to open it again 2 months later, so yeah I replaced them all.

[Aldo22]

Yes, the shipping costs...
The store here with halfway reasonable shipping costs only has PEC12R-4220F-S0024 in stock, i.e. the one with the 24 detents.
You said:

After thinking it twice, I'll avoid the mechanical steps in the small encoders, adjusting certain values require a lot of turning, dealing with a ton of clicking will make the experience even worse!

Since the original big knobs have 12 mechanical steps and are pretty tough to turn, I would like to ask you if the Bourns PEC12R with 24 detents (Which you have installed for the big knobs?) would be acceptable for the V0 too? Or are they too hard to turn?

Thank you!

[DavidAlfa]

They work well. I put 24 steps everywhere, but didn't put detents on v0 and trigger, would be annoying.

[Aldo22]

They work well. I put 24 steps everywhere, but didn't put detents on v0 and trigger, would be annoying.

So you wouldn't recommend these for the V0.

Well, then I'll wait for a good opportunity for one with "Detent Option 0 = No Detents"
The other stores here charge a flat rate of more than € 20 for shipping alone.
That's too much for a $130 scope.
Maybe I'll need something else soon so that it's worth ordering there.
The price on Aliexpress is also absurd.

Thank you!

[DavidAlfa]

Just think: Will you enjoy a lot of brrrrrrrr when moving V0 to adjust anything? I don't think so?
Check RS-Online, here in Spain it has the best shipping rates.

Thanks for the tip! I haven't looked at this store yet.
But as far as I can see, they don't have the desired encoder either:

[DavidAlfa]

Did you read everything? I had the same problem, the solution is very simple! Just buy the 4225 and cut  ~2mm off the shaft.

If not being able to source them, the PEC12R-4225 (12mm shaft) will almost fit, the small caps have a depth of 12mm while the large ones have 11.2mm, it would only require trimming a bit off the shaft end.

Yes, thank you. I had seen it.
I'll probably do it that way, I was just hoping to get the exact model at a reasonable shipping price.
It does exist here at Mouser or Digikey, but the delivery costs are too high.
