VISA Example in Python (PyVISA 1.5 and older)
You can use the Python programming language with the PyVISA package to
control Keysight Infiniium Series oscilloscopes.
The Python language and PyVISA package can be downloaded from the web at
http://www.python.org/ and http://pyvisa.sourceforge.net/ , respectively.
To run this example with Python and PyVISA:
1
Cut-and-paste the code that follows into a file named "example.py".
2
Edit the program to use the VISA address of your oscilloscope.
3
If "python.exe" can be found via your PATH environment variable, open a
Command Prompt window; then, change to the folder that contains the
"example.py" file, and enter:
python example.py
