Hi. I have been started using AFR method implemented in PNA network analyzer.
As a newbie I tested this method with two fixture.
For FixtureA AFR de-embedding method gives reliable result for most combination standards.
But for FixtureB I couldn't get any valid result.
I allowed myself to attached pdf file with compared both.
Kindly please comment. I would be happy to know the guidelines and hints for design fixture for AFR method for future.
If you have any questions or you need a more data, I am ready to provide you .
