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.
