OpenHantek6022

OpenHantek6022 is a free software for Hantek DSO6022 USB digital signal oscilloscopes that is actively developed on github.com/OpenHantek/OpenHantek6022 - but only for Hantek 6022BE/BL and compatible scopes (Voltcraft, Darkwire, Protek, Acetech, etc.).

This project gives no support for its currently unmaintained predecessor openhantek.

About OpenHantek6022

• Supported devices:
• Hantek 6022BE and 6022BL as well as compatible scopes (e.g. Voltcraft DSO-2020).

• SainSmart DDS120 (thx msiegert) - this device has a different analog front end and uses the slightly improved sigrok firmware, which has some limitations compared to the Hantek scopes (see #69).

• Demo mode is provided by the -d or --demoMode command line option.

• Fully supported operating system: Linux; developed under debian stable (currently bookworm) for amd64 architecture.
• Raspberry Pi packages (raspbian stable) are available on the Releases page, check this setup requirement.
• Compiles under FreeBSD (packaging / installation: work in progress, thx tspspi).
• Other operating systems builds: Windows (mostly untested) & macOS (completely untested). No support for non-Linux related issues unless a volunteer steps in!
• 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 channels.
• 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, DC (average), AC, RMS and dB (of RMS) values as well as frequency of active channels. Display as dBV (0 dBV = 1 V rms), dBu (0 dBu = 1 mW @ 600 Ω) or dBm (0 dBu = 1 mW @ 50 Ω) can be selected in Oscilloscope/Settings/Analysis.
• Display the power dissipation for a load resistance of 1..1000 Ω (optional, can be set in Oscilloscope/Settings/Analysis).
• Display the THD of the signal (optional, can be enabled in Oscilloscope/Settings/Analysis).
• Show the note values and deviation in cent (twelve equal, A = 440 Hz) for audio frequencies (optional, can be enabled in Oscilloscope/Settings/Analysis). Useful to tune e.g. your electrical guitar.
• Math channel modes: CH1+CH2, CH1-CH2, CH2-CH1, CH1*CH2 and square, abs, sign, AC and DC part of CH1 or CH2.
• Time base 10 ns/div .. 10 s/div.
• Sample rates 100, 200, 500 S/s, 1, 2, 5, 10, 20, 50, 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).
• Hardware input gain automatically selected based on vertical sensitivity: 1x (up to ±5 V for 1, 2 or 5 V/div), 2x (up to ±2.5 V for 500 mV/div), 5x (up to ±1 V for 200 mV/div) and 10x (up to ±500 mV for 20 or 50 mV/div).
• Downsampling (up to 200x) increases resolution and SNR.
• Calibration output square wave signal frequency can be selected between 32 Hz .. 100 kHz in small steps (poor person's signal generator). A little HW modification provides a jitter free HW-driven calibration output signal instead of the interrupt driven SW-output.
• Trigger modes: Normal, Auto and Single with green/red status display (top left).
• Untriggered Roll mode can be selected for slow time bases of 200 ms/div .. 10 s/div.
• Trigger filter HF (trigger also on glitches), Normal and LF (for noisy signals).
• Display interpolation modes Off, Linear, Step and Sinc.
• Calibration values loaded from eeprom or a model configuration file.
• Online offset calibration creates a configuration file for persistent data storage.
• 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 JPG, PNG or PDF file or to the printer; data export as CSV or JSON.
• 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 800*300 for old laptops or workstation computers.
• All settings can be saved to a configuration file and loaded again.
• French, German, Russian and Spanish localisation complete; Chinese, Polish and Swedish is updated regularily; Italian and Portuguese translation ongoing - volunteers welcome!

AC Coupling

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

Continuous Integration

Every commit triggers a workflow on GitHub Actions that builds and packages OpenHantek6022 for: * Linux (*.deb, *.rpm, *.tar.gz) * Windows (*_mingw_x64.zip, *_msvc_x64.zip) * macOS - (*.dmg, *.tar.gz)

This status badge here (and on top) show the build status.

Building OpenHantek6022 from source

The preferred way to run OpenHantek6022 is to build it from source on your system, especially under Linux.

The easiest way to get an up-to-date working code base is to clone the code from here via

git clone https://github.com/OpenHantek/OpenHantek6022.git

and then build it locally, for this you will need the following software: * 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, Raspberry Pi, FreeBSD, Apple macOS and Microsoft Windows.

To make building for Linux even easier, I provide two shell scripts: * LinuxSetup_AsRoot, which installs all build requirements. You only need to call this script once (as root) if you have cloned the project. * LinuxBuild configures the build, builds the binary and finally creates the packages (deb, rpm and tgz) that can be installed as described in the next paragraph. If you make small changes to the local source code, it is sufficient to call make -j4 or fakeroot make -j4 package in the build directory.

Install Prebuilt Binary Packages

• Download Linux (Ubuntu 2204 LTS), Raspberry Pi (Debian stable), FreeBSD (12.1), macOS (12.7) and Windows (MINGW / MSVC2022) packages for your convenience from the Releases page.
• If you want to follow ongoing development, packages built from a fairly recent commit are available in the rolling devdrop release. Individual features or elements of the GUI may still change.
• For RPi4 see also issue #28.
• These binary packages are built on stable operating system versions and require an up-to-date system.
• As I develop on a Debian stable system my preferred (native) package format is *.deb. The program itself and the *.deb package built on my local system is tested for completeness and correctness. The precompiled packages are only randomly tested - if at all - and the installation of the *.rpm packages is untested.
• To install the downloaded *.deb package, open a terminal window, go to the package 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.
• The *.tar.gz achives contain the same files as the *.deb and *.rpm packages for quick testing - do not use for a permanent installation. Do not report any issues about the *.tar.gz!
• Get macOS packages from macports - thx ra1nb0w.
• Get Fedora rpm packages - thx Vascom.
• Download (untested) builds from last commit(s). Select the preferred workflow run and go to Artifacts.

Run OpenHantek6022

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

You can explore the look and feel of OpenHantek6022 without the need for real scope hardware by running it from the command line as: OpenHantek --demoMode.

Note: To use the 6022BL in scope mode, make sure the "H/P" button is pressed before plugging in.

Using Hantek 6022BL LA Function

The Hantek6022BL can either be used as oscilloscope or as logic analyzer, but not both at the same time - it is not a mixed-signal-oscilloscope (MSO). If you want to use the LA part, then sigrok is the way to go, it works (besides Linux) also for MacOS and Windows. There is no point in supporting the LA input from OpenHantek.

Offset Calibration

The oscilloscope has quite
