Hi all,
I currently use the N5225A. I had a basic question regarding a 4 port VNA, and if 2 sources are required.

In general I am using my N5225A to measure full 4 port s-parameters (insertion, return loss) of a differential passive network. In general do 4 port VNAs has a single or dual source. If they have a dual source what is the advantage?

regards,
Guy
