Hi, from the following link :
http://www.av.it.pt/medidas/data/Ma...rview/Screen_Elements/Polar_chart_example.gif
There is a polar diagram in VNA(Vector Network Analyzer)
We are able to know the PCB layout trace length by phase variation.
My questions are :
1. How to operate ? I have found several VNA handbooks, but I have not found the
operation process.
2. What’s the detailed principle ? Why can we know the PCB layout trace length by phase variation?
Where can I find these information ? Such as books, application Note, data sheet, or the key words that I should google ?
Thanks a lot~!
