SCPI.NET Example in IronPython
You can also control Keysight oscilloscopes using the SCPI.NET library and Python
programming language on the .NET platform using:
• IronPython (
http://ironpython.codeplex.com/ ) which is an implementation of
the Python programming language running under .NET.
To run this example with IronPython:
1
Install the Keysight Command Expert software and the command set for the
oscilloscope.
2
Cut-and-paste the code that follows into a file named "example.py".
3
Edit the program to use the address of your oscilloscope.
4
If the IronPython "ipy.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:
ipy example.py
