New Hantek DSO2X1X models?

[Aldo22]

A scope is not a DMM and shouldn't be treated as such.
This tests make no sense.

You're right, but since it has a "DVM" window, it kind of pretends to have that feature.

At least I'm not making a video about it. 

[DavidAlfa]

It does work close enough, but within certain limits.
Typical accuracy is 0.2-0.4 divisions.

Yes. I didn't expect better accuracy, I just wanted to make sure it wasn't "light years" off.

But what I still don't understand is the interpretation of amplitude vs peak-to-peak.
As a newbie, I thought that Amplitude = Vpp without overshoot.
But I don't see that in the measurements.
Am I wrong or is it the Hantek?

[Aldo22]

Hi, I'm still trying to understand the Hantek.
is there any difference between acquire type equivalent-time and real- time?
I have not been able to find any difference.
Thanks!

[Aldo22]

is there any difference between acquire type equivalent-time and real- time?

According to the information I've found, this is somewhere between "obsolete" and "not implemented".
I don't really understand why this option is there, but I think it's best to forget about this "feature".

[Aldo22]

The only true fact I know of is they ship a 100MHz or 150MHz proble with each version!
They seem to not have any real difference in HW.

I have checked this with a rise-time measurement and think that there is actually no difference to the 150MHz version.

So far I'm very happy with the purchase.
Of course, not everything is perfect, but you get a lot for your money with the DSO2C10.

Thanks again!

I have purchased a DSO02C10 from Banggood some weeks ago. It arrived with the latest software apparently. I was able to upgrade it to 2D15 with the "do_other_update" method. The dso3kb_FW3205_B205.upk did not work for me: it successfully ran, but nothing was changed. The older FW .upk-s did not work either: ran sucessfully and after restart nothing has been changed.

Thank you for the great job of DavidAlfa and all the others made it possible.
God bless you all.

[DavidAlfa]

FW has nothing to do with the model.
Did you read the FAQ?

This year, Santa Claus was generous and gave me a DSO2C10 oscilloscope. I have already made a backup and upgrade to 2D15. I was lucky and the generator was present on the pcb. Here are the software versions it came with: Software 1.0.3.0.0(230831.00)
Hardware 003.002.001.000.000.000.000.000 Firmware 3205
On the PCB, the marking DSO2D15_V1.7 2021.1.14

The first thing I noticed is that my power supply is different than I saw on the Internet, it has a different SMPS controller. And in my case it is +7V/-7V and not +8V/-8V as before.

This is my first post on the Forum, but generally speaking, I have been working in electronics for over 30 years. Greetings to everyone.

[DavidAlfa]

Yes, there's a revised PSU in latter models.

[Aldo22]

The first thing I noticed is that my power supply is different than I saw on the Internet, it has a different SMPS controller. And in my case it is +7V/-7V and not +8V/-8V as before.

I also have one of these PSUs and don't see any worrying noise even at 2mV/div.
A little in normal acquire mode and almost nothing in HR mode. (Nothing connected).

[eurotips]

I saw somewhere on cxem.net a conversion to a linear power supply. There wasn't much difference. Maybe Hantek improved the quality of the built-in power supply.
Maybe it will heat up less at +/-7V. Anyway, I added heatsinks on the ADC, FPGA and F1C200.

[Aldo22]

Maybe Hantek improved the quality of the built-in power supply.

I think so too, because noise is not an issue with my version.
If it was less noisy at 2mV/div, I would think it had crashed. 
In any case, I wouldn't think of trying to improve anything in this area.

[Aldo22]

I have just looked at the DSO2000 specs again.

Overvoltage Category: 300V CAT II
Maximum Input Voltage:300VRMS (10X)

What does this mean: "300VRMS (10X)"?
30VRMS @1X?

That would be less than what the Zeeweii can handle.
Really?

[Aldo22]

Does nobody really know how many volts the Hantek can withstand on the BNC?
I'm not at all concerned about my safety as I don't work with mains, I just want to know whether I'll damage my scope if I have 40 volts on the alligator clip or the 1x probe, for example.

Should I ask in the beginners' forum?

I've read some stuff but I'm not quite sure if I understand it right and I want to be sure.

Somehow there are different aspects and I don't know exactly what the values refer to.

- CAT rating seems to be more for the protection of people.
- The maximum the scope can display (10Vpp x 8 in my case).
- What can the probes withstand? (600Vpk x10 and 200Vpk x1 in my case).
- What interests me: At what voltage on the BNC will my scope be damaged?

While the description of my scope only says this:

Overvoltage Category: 300V CAT II
Maximum Input Voltage:300VRMS (10X)

the manual of another Hantek scope says something similar, but with an addition:

CAT I and CAT II 300VRMS (10×), Installation Category
CAT III 150VRMS (1×)

So the answer could be 150Vrms?

Thank you!

Received my new new DSO2C10. Added some components from brocken premium psu:
x and y capacitors right on power socket, ferrites - the ring near switch button and clip-on ferrite on +-7v flat cable. Also added copper shield to the transformer.
2mv high frequency noise level was redused in about 2 times.

[nycn]

Added the metal shield to psu
CH1 nothing connected
CH2 PP-150 probe X1

Obviously no needs for lps

[Aldo22]

Looks great!
But do you also have screenshots of "before"? Was there much more noise before?
My unit shows comparable results without any changes.
(attached HR/BW).

[nycn]

On your screen CH1 connected ?
I didn't save initial images, just remember visually - the noise of connected CH2 was about two times or more bigger comparing with non connected CH1

The Hantek PP-150 probe is connected to Ch2, but it's not short-circuited like in your case.
When I connect the crocodile clip with the probe tip, I see a few spikes, but not necessarily a larger base noise level.
I'm not experienced enough to judge that.

[Aldo22]

By the way, the Hantek has a statistics mode.
This is perhaps a little more informative, as a screenshot only ever shows a specific moment (-> Avg)

How high is the current consumption in  +5/+7/-7V lines in the new version of the power supply?

Hi all,

i've a question for the forum ..
I running on my pc linux ubuntu 20.04 lts 
Exist software linux for Hantek DS02xx oscilloscope?
I've found OpenHantek, but seem not corrtect for this series.

Thanks

Roberto iw2evk

[Aldo22]

Have you tried it?
It says "Supported devices: DSO2xxx Series".
https://github.com/OpenHantek/openhantek

There is Keysight IO Libraries Suite for Linux, which seems to be the basis for the Hantek applications. 
Not sure how useful.

Mhh..
i try it in the christmas holidays..
Thanks
