This python library/application allows to control Rigol DS1000 / DS2000 series oscilloscopes as well as the function generator DG1022.
It uses universal_usbtmc for the communication with the device. This allows to use different backends to connect to your device:
- RS232
- USBTMC:
- Linux Kernel Driver
- python-usbtmc
- TCP Socket (via rpi-usbtmc-gateway)
First, install universal_usbtmc
pip install https://github.com/pklaus/universal_usbtmc/archive/master.zip
Then install PyOscilloskop
pip install https://github.com/pklaus/PyOscilloskop/archive/master.zip
Depending on the backend you want to use, you may have to install additional software. Read the universal_usbtmc README file for more information.
You can either import the modules found in this Python package in your own scripts to automate control / measurements.
Or use the tools that ship with this software:
pyoscilloskop-cli- A CLI tool for the scopes
Captures the current waveforms and displays them with Matplotlib and/or saves them to an image file.pyoscilloskop-web- A web GUI for the scopes
Starts a web server allowing to display waveforms in the browser.
Examples of how to use the different backends with the tools:
To run the CLI tool with the linux_kernel backend, run:
rigolCli.py --backend linux_kernel /dev/usbtmc0
To start the web server with the tcp_socket backend, connecting to the host 192.168.0.21, run:
pyoscilloskop-web --backend tcp_socket 192.168.0.21
To run the CLI tool with the python_usbtmc backend and enable debug mode, run:
rigolCli.py --backend python_usbtmc "USB::0x1ab1::0x0588::INSTR" --debug
To start the web server with the pyserial backend, using the serial device /dev/ttyUSB0
(don't forget to set your scope to 38400 baud!):
pyoscilloskop-web --backend pyserial ASRL::/dev/ttyUSB0,38400::INSTR
This software started as a fork of sbrinkmann / PyOscilloskop.
