Subject: Re: [HP-Agilent-Keysight-equipment] Mixing 'n' matching S parameter test sets? S parameters, as you know, can be characterized by S11, S21, S12 and S22. The two port test sets have enough directional couplers and power splitters inside to measure all four, by switching the direction of the RF feed, if directed to do all four measurements by the VNA controller. However, the 8754A was built long before that became a necessity for fast bench measurements. There are still just two ports on the test set, I am sorry if I confused the topic. I meant four S parameters being measured.
