Hantek 6022BE 20MHz USB DSO
horo:
Hi,
My active branch has moved to the OpenHantek project on github to bundle all activities in one place.
https://github.com/OpenHantek/OpenHantek6022
Latest release v2.01 has some improvements, most important: No freeze of user interaction when sampling is paused. Now you can e.g. measure, pause, change gain and offset and finally create a png/pdf or csv.
Works on linux and macOS.
WANTED: Windows volunteer testers.

Another big step: OpenHantek6022 now only supports 6022BE and 6022BL, all older devices (2090, 2150, 2250 and 5200) have been removed (because I don't own any of these devices and can't test them). Also, these devices behave very differently in USB communication and require a variety of switch cases and #defines and inflate the code unnecessarily. The good result is that OpenHantek6022 is now completely free open source - all nonfree Hantek firmware is now removed. 6022 has been using my free open source firmware already for quite some time.
New feature: A check box for the included X10 probes, now the measurement and display doesn't have to be converted anymore - a simplification especially for hobby users and beginners.

P.S.: The nasty amplitude "pumping" of the spectrum trace is fixed with v2.08 - now I display the _magnitude_ of the spectrum (i.e. sqrt( real*real + imag*imag )) instead of the real part only of the complex result of the discrete fourier transform. -> read more.
P.S.: Version v2.09 allows slower timebases 20, 50 and 100 ms/div with increased sample sizes up to 200 kS (-> 2 s sample time).
P.S.: Version v2.10 uses downsampling (100kS/s down to 10, 20, 50 kS/s) to increase the SNR for low frequency measurement (e.g. audio). It also ensures the loading of the up-to-date firmware if an older firmware was uploaded previously into the scope RAM (e.g. by using an older OpenHantek version or the Hantek original software without unplugging the device afterwards).
P.S.: v2.11-rc1 is available for testing.
P.S.: v2.11-rc2 uses 10x downsampling on slow samplerates (<= 1MS/s) (gives about 10 dB better SNR).

Hi,
v2.11 is available, main enhancement is the AC math mode that allows to calculate the AC part of Ch1 or Ch2 and display it in higher resolution. It's not a real AC mode (missing due to stupid HW limitation) but allows to have a better look at small AC signals with moderate DC offset, see attached screen shots of a 2.5 V eff sine with +50 V DC offset. The function generator was adjusted so that the scope's input range (+- 50V with 1:10 probe) was slightly exceeded, see the red clipping indicator bottom left.
I checked also the windows build in a virtual W7 machine and it doesn't show obvious glitches (beside the slower performance due to virtualisation).
Have fun

Hi,
I recently installed, under Windows 10 and XP, the Hantek 6022BE oscilloscope. Unfortunately the FFT function included in the Hantek software has several problems (horizontal axis is badly defined in frequencies, peaks values of frequencies are unreadable...). Chance made me discover your OpenHantek6022 software, which seem particularly interesting. But, i could not install the libUSB and winUSB drivers under Windows 10 which display the following error messages:
"The file libusb-1.0.21-win.7z can not be opened as an archive"
"The compressed winusb driver.zip folder is not valid".
Please excuse-me for my poor english, and thank you by advance for your help.

Hi,
My previous problems with libusb-1.0.21-win.7z104 kO and winusb driver.zip 4707 kO are now solved. These two files were corrupted. I have installed LibusbK using zadig-2.4.exe on my PC (ACER Aspire M3400 2.60 GHz RAM 16 Go, X64) running under Windows 10 family version 1709. Then i shut down the computer and restart.
OpenHantek-Win-x86-Release-b67 had been installed before. Every thing up to now seem OK. To morrow, i will begin the tests, and i will give you more information later.
