OpenHantek6022

OpenHantek6022 is a free software for Hantek and compatible (Voltcraft/Darkwire/Protek/Acetech) USB digital signal oscilloscopes. It was initially developed by David Gräff and others on github.com/OpenHantek/openhantek. After David stopped maintaining the programm I cloned the repo to provide updates - only for Hantek 6022BE/BL.

Supported devices: Hantek 6022BE and 6022BL as well as compatible scopes (e.g. Voltcraft DSO-2020) and SainSmart DDS120 (thx msiegert).
Fully supported operating system: Linux; developed under debian stable for amd64 architecture.
Raspberry Pi packages (raspbian stable) are available on the Releases page.
Compiles under FreeBSD (packaging / installation: work in progress, thx tspspi).
Other operating systems builds: Windows (partly tested) & MacOSX (untested).
Uses free open source firmware, no longer dependent on nonfree Hantek firmware.
Extensive User Manual with technical specs and schematics.

Features

Voltage and Spectrum view for all device supported chanels.
CH1 and CH2 name becomes red when input is clipped (bottom left).
Settable probe attenuation factor 1..1000 to accommodate a variety of different probes.
Measure and display Vpp, RMS, DC (average), AC (rms) and AC as dB values as well as frequency of active channels.
Math channel modes: CH1+CH2, CH1-CH2, CH2-CH1, CH1*CH2 and AC part of CH1 or CH2.
Time base 100 ms/div .. 10 ns/div.
Sample rates 100, 200, 500 kS/s, 1, 2, 5, 10, 12, 15, 24, 30 MS/s (24 & 30 MS/s in CH1-only mode).
48 MS/s not supported due to unstable USB data streaming.
Downsampling (up to 100x) increases solution and SNR.
Downsampling sample rates 10, 20, 50 kS/s.
Calibration output square wave signal frequency can be selected between 50 Hz .. 100 kHz in 1/2/5 steps.
Trigger modes: Normal, Auto and Single with green/red status display (top left).
Calibration values loaded from eeprom or a model configuration file.
Calibration program to create these values automatically.
Digital phosphor effect to notice even short spikes; simple eye-diagram display with alternating trigger slope.
Histogram function for voltage channels on right screen margin.
A zoom view with a freely selectable range.
Cursor measurement function for voltage, time, amplitude and frequency.
Export of the graphs to CSV, JPG, PNG file or to the printer.
Freely configurable colors.
Automatic adaption of iconset for light and dark themes.
The dock views on the main window can be customized by dragging them around and stacking them. This allows a minimum window size of 640*480 for old workstation computers.
All settings can be saved to a configuration file and loaded again.

AC coupling

A little HW modification adds AC coupling. OpenHantek6022 supports this feature since v2.17-rc5 / FW0204.

Install prebuilt binary

Download Linux, Raspberry Pi, Win and MacOSX packages from the Releases page. (the Win and MacOSX packages are not tested, neither is the installation of the *.rpm packages).
To install the downloaded *.deb package, open a terminal window, go to the download directory and enter the command (as root) apt install ./openhantek_..._amd64.deb. This command will automatically install all dependencies of the program as well.
For installation of *.rpm packages follow similar rules, e.g. dnf install ./openhantek-...-1.x86_64.rpm.
Get MacOSX packages from macports - thx ra1nb0w.
Get Fedora rpm packages - thx Vascom.
Download (untested) Windows build from last commit.

Building OpenHantek from source

You need the following software, to build OpenHantek from source:

CMake 3.5+
Qt 5.4+
FFTW 3+ (prebuild files will be downloaded on windows)
libusb-1.0, version >= 1.0.16 (prebuild files will be used on windows)
A compiler that supports C++11 - tested with gcc, clang and msvc

We have build instructions available for Linux, Apple MacOSX and Microsoft Windows.

Run OpenHantek

On a Linux system start the program via the menu entry OpenHantek (Digital Storage Oscilloscope) or from a terminal window as OpenHantek.

OpenHantek6022 runs also on legacy HW/SW that supports at least OpenGL 2.1+ or OpenGL ES 1.2+. OpenGL is preferred, if available. Overwrite this behaviour by starting OpenHantek from the command line like this: OpenHantek --useGLES.

Raspberry Pi uses OpenGL ES automatically.

USB access for the device is required:

As seen on the Microsoft Windows build instructions page, you have to assign an usb driver to the device. The original Hantek driver doesn't work.
On Linux, you need to copy the file utils/udev_rules/60-hantek.rules to /etc/udev/rules.d/ or /lib/udev/rules.d/ and replug your device. If OpenHantek is installed from a *.deb or *.rpm package this file is installed automatically.

Important!

The scope doesn't store the firmware permanently in flash or eeprom, it must be uploaded after each power-up and is kept in ram 'til power-down. If the scope was used with a different software (old openhantek, sigrok or the windows software) the scope must be unplugged and replugged one-time before using it with OpenHantek6022 to enable the automatic loading of the correct firmware. The top line of the program must display the correct firmware version (FW0204).

Specifications, features, limitations and developer documentation

I use this project mainly to explore how DSP can improve and extend the limitations of this kind of low level hardware. It would have been easy to spend a few bucks more to buy a powerful scope - but it would be much less fun :) Please refer also to the developer documentation pages.

Contribute

We welcome any reported Github Issue if you have a problem with this software. Send us a pull request for enhancements and fixes. Some random notes:

Read how to properly contribute to open source projects on GitHub.
Create a separate branch other than master for your changes. It is not possible to directly commit to master on this repository.
Write good commit messages.
Use the same coding style and spacing (install clang-format. Use make target: make format or execute directly from the openhantek directory: clang-format -style=file src/*).
Open a pull request with a clear title and description.
Read Add a new device if you want to know how to add a device.
We recommend QtCreator as IDE on all platforms. It comes with CMake support, a decent compiler, and Qt out of the box.
