OpenHantek6022 is a DSO software for Hantek USB digital signal oscilloscopes 6022BE / BL. Development OS is Linux, but I got the feedback that the program also works under MacOSX and Windows.

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 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).
  • Fully supported operating system: Linux (developed under debian stable).
  • 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.


  • Voltage and Spectrum view for all device supported chanels.
  • CH1 and CH2 name becomes red when input is clipped (bottom left).
  • Checkbox for X10 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.
  • 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.
  • A zoom view with a freely selectable range.
  • Cursor measurement function for voltage, time, amplitude and frequency.
  • Export to CSV, JPG, PNG or print the graphs.
  • Freely configurable colors.
  • 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.

Building OpenHantek from source

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

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

Run OpenHantek

With the original OpenHantek version you needed an OpenGL 3.2+ or OpenGL ES 2.0+ capable graphics hardware. OpenHantek6022 runs also on legacy HW/SW (OpenGL 2.1+ or OpenGL ES 1.2+) with the patch coozoo@01b42d3 OpenGL is preferred, if available. Overwrite this behaviour by starting OpenHantek from the command line like this: OpenHantek --useGLES.

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 firmware/60-hantek.rules to /etc/udev/rules.d/ or /lib/udev/rules.d/ and replug your device.


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 (FW0202).
