SCPI.NET Example in IronPython
You can also control Agilent 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 Agilent 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:
