Hantek DSO2000 Master Thread (DSO2C10 DSO2C15 DSO2D10 DSO2D15)

I have observed that if I plug it in directly without the alligator cable that comes with the oscilloscope, the peaks on the sides of the signal improve, but I do not get a clean signal like yours.

Yes, the noise and all that doesn't originate in the scope, it's from the cable or the probe.

You can minimize all that with a short/better cable.

In the attachment you see the short coax from the TinySA or NanoVNA and a 50Ohms LR.

You can measure signals below 1mVpp cleanly this way (second picture, the resolution starts to show, but not so much the noise).

With a probe, you probably pick up most of the noise from the screen. Stay away from it.

The scope does not "invent" the noise. If it's there, it shows it.

However, it has no “intensity grading” like newer Rigols.
So:
- Take the cable away from sources of interference
- Turn on the 20M bandwidth limitation if possible.
- With Acquire Mode “Average” repeating signals may also appear more stable.
- In 1x mode of the probe you will have less noise.
- If the noise is so bad that it cannot trigger stably, you can adjust the holdoff of the trigger for periodic signals.
  This is best done via SCPI, as it is sometimes not possible to make fine adjustments with the rotary knob (bug).

AliExpress had an offer of £15 off spending over £129. Found a DSO2C10 with an extra probe for £129.05 including delivery. -£15 +20% tax (VAT) = £137 all in, which seemed pretty good to me.
Nothing new on the SW/FW front, seems latest of those available.
Working through some of the suggested mods. Function Generator works!
@DavidAlfa ... I can't thank you enough for the work you put into this.

Hello and thanks for your very detailed post.

I have a simple question, what can I do if the USB port in the front of the DSO2D10 isn't operative, there is some another manner of doing updates or trying to repair software problems? I have my instrument freeze after power on and no button of the interface is working.
I try reset factory and this does not help.

Have you some suggestion? 

Thank you and have a nice day!

[Aldo22]

If you have tried everything listed under "Recovery" on the previous page, then I would contact the vendor or Support@hantek.com or zhangqiang@hantek.com.

P.S. The front USB only works when the rear one is unplugged.

[ereides]

Thank you for your kindly response,
In my case the front USB isn’t working even when the rear USB is disconnected. May be some hardware trouble?
Thank you again!

[Aldo22]

I don't quite understand your situation.
Is your problem that the device is freezing or that the front USB is not working?
Is it immediately freezing or is it running for a while?
Does it freeze again when you restart it immediately?
If it freezes immediately, how do you know if the front USB is working?
Did you do anything special before the problems occurred?

 Well, after a short period of time with the oscilloscope 2D15 I changed it for the Rigol DHO802 and the change has been like overnight. The only bad thing about the Rigol is the startup time, otherwise it is another world. There are no shaky images and the response is much smoother than the Hantek. Not to mention the touch screen that makes everything much simpler and more intuitive. Very happy with the change, the 12bits are very noticeable. I move to the Rigol section. Greetings

Congratulations!
I just always wonder why you don't buy a Rigol / Siglent right away if the price doesn't matter.
Where I live, I can get three DSO2000s for one DHO802.
Of course the Rigol / Siglent is better, anything else would be very strange.

[Elextro]

Well, it turns out that price does matter, because first I had to sell the Hantek and something else to be able to buy the Rigol. Otherwise my wife kicks me out of the house.

Hi, could you point me to the £15 off if it's still valid?

Also did you get charged any import taxes to UK? I thought max was £125 before they started to charge you import tax. Thanks

One of the cheapest stores is this one:

At Aliexpress there are often "Welcome deals" or "Choice days", where it gets even cheaper.
