I am evaluating a special 2-port matching network device over a wide frequency span. The termination impedance on one side of the device is 50ohm, and on the other side is frequency dependent, e.g. antenna impedance. I can use load-pull tuner to mimic this frequency dependent load but I have to change the tuner’s setting for each frequency point. It is a slow process to scan the entire spectrum and every time I adjust the matching network, I have to repeat the whole process before I can know if I tuned into the right direction. So I am wondering if the fixture simulator of the network analyzer can help me on this. Right now, I have an E5071B in the lab, the Port Zconvertions only allows me to put in a fixed impedance value for each port. It doesn’t allow me to load the S-parameter file or impedance data file. I am wondering if there is way to load the S-parameter file into the port of the network analyzer. I notice that De-Embedding and Port-matching functions can load user defined S-parameter files into the network analyzer. Does this require special VBA programs or firmware change?

This is part of the analzyers fixture simulator functions. It is already in the firmware of every E5071C, and in E5071B with revision 3.50 or greater. Most E5071B's will have this installed already. So, you probably do not have to update or use a .vba
