It has some nice features and performance for its price. To visualize actual data, I helped things along with the command line to massage the output a bit and save it to a file by doing. I did not see any improvement tough, so I think this mod is a waste of money, but at least confirms the part number. The ADCs are humming along filling and refilling the 32K of ram one for each channel in this example. Channel two seems to work fine on the whole range. Thanks for all the useful information and good conversation! Ok, but you should really open a thread on the openhantek forum here:

Getting the Hantek DSO working with Linux –

I think that removing the call to the transform in OpenHantek will make the trigger much more erratic — especially when moving the trigger point around. Notify me of new comments via email. This conversation is just gettting interesting: I think the hardware gives a lot of bang for the buck and is of great value for any serious hobbyists who can t afford a bench top model.

The scope is realized with a standard 1. I use it on DC mostly and I would like to be able to have the traces match for comparisons. What I was expecting to happen is a rise in the base noise on the samples, but by just looking at the signals on OpenHantek I was not spotting any significant difference.


But if the algorithm is so wrong I would expect to see the triggered edge jump around as I manually move the triggerpoint along sample. Fabio, please file a bug report for that segfault you saw. You are commenting using your Facebook account. Can you confirm or refute this on your system using openhantek? Thanks for the tip about sigrok support!

This device is not working and PC is faulty. When I overlay both channels the glitch shows up identically on both.

DSO linux driver | All About Circuits

Curiously enough, the resistor is actually shorted with linus 0 Ohm, so the designer decided to use the actual internal circuitry of the as part of the filtering. It could of course have been me also messing up things in my build, for whatever reason.

The original article is now 3 y. Yeah, I linix the comparison as well at the time. You can probably just fit one and the missing resistors on the or just use an inline BNC attenuator.

Unfortunately, and even thought I followed the instructions carefully, I never managed to install the software on my Xubuntu 3. Trigger normal on — edge and trigger at 1. This especially with regard to autodependcies. Maybe you can ask the sigrok developer who did dso-20090 commit: In any case, most of what I see myself doing with this scope is more along the lines of this screenshot:. Still udev or what else should recognize the DSO not working.


Ok, but you should really open a thread on the openhantek forum here: Was probably a bad solder joint then, with a bit of luck it should work fine for a while! This information gets sent to the that is running the downloaded driver.

How to use the Hantek DSO-2100 USB oscilloscope in Linux

Implement bandwidth limiting filter on both channels and HF rejection filter on trigger Implement calibration for fastrate, including DSO OpenHantek installed on Linux. I just copied the Javascript embedding link and pasted it in the body of the comment.

If anything they should publish the low level interface to the board and make it easy to work with. Seems like that would cause the same propagation delays as using logic gates on outputs of a conventional counter as described above.

How about the trigger? What would you guys suggest to try next?
