Quick start (Windows/Mac/Linux)

1. Plug Haasoscope Pro into your computer via USB C
2. Download code and unzip it: https://github.com/drandyhaas/HaasoscopePro/archive/refs/heads/main.zip
3. Run HaasoscopeProQt in the HaasoscopePro/software/dist/(OS)_HaasoscopeProQt directory

Tips

• If not enough power is supplied or issues happen during readout, plug in via a powered USB hub or use a 12V power adapter
• If the board is not found on Linux, try: sudo rmmod usbserial ftdi_sio

Fuller way of running

1. Install python3 and git (operating system dependent)
2. Install dependencies:
   pip3 install numpy scipy pyqtgraph PyQt5 pyftdi ftd2xx
3. Get code:
   git clone https://github.com/drandyhaas/HaasoscopePro.git
4. Install FTDI D2xx driver
   for Windows: install using the setup exe
   for Mac can just do: sudo cp HaasoscopePro/software/libftd2xx.dylib /usr/local/lib/
   for Linux can just do: sudo cp HaasoscopePro/software/libftd2xx.so /usr/lib/
5. Run:
   cd HaasoscopePro/software
python3 HaasoscopeProQt.py
6. To remake exe for quick start:
   pip3 install pyinstaller # install dependency once
   python3 -m PyInstaller HaasoscopeProQt.py
mv dist/HaasoscopeProQt dist/(OS)_HaasoscopeProQt

Repository structure

• adc board: Design files and documentation for the main board, based on Eagle 9.6.2
• adc board/Kicad: An import of the main board design files into KiCad 8
• adc board firmware: Quartus lite project for the Altera Cyclone IV FPGA firmware
• case: Front and back PCB panels for the aluminum case
• software: Python files for the oscilloscope program
• sub boards: Eagle design files and documentation for smaller test boards that were used during development

2 GHz Active Probe

All designs for the accompanying active probe are in a separate repository

Editing the GUI

The Haasoscope Pro GUI can be edited using Qt Designer, started with:
pip install pyqt5-tools
pyqt5-tools designer
Then open software/HaasoscopePro.ui or HaasoscopeProFFT.ui etc.
