I have a question about some older bugs and limitations, were they fized or not?
1. It was not possible using complex power source impedance. Even when defined with “i”, only its real part was treated. Can we use complex sources(loads) now? It is essential when modelling real devices, like antenna frontends. (have you ever seen an antenna with wideband purely real impedance? I guess, only in 1st course textbook)
2. Since it is often essential matching to real measured load/source, there was a feature in [S-parameters] block, called “ComplexZ”. Ideally, it should have converted the simulated fixed-Z port into the measured frequency dependent complex impedance port reprezentation, with the VNA-acquired data.
But it was not working. I mean, people, including developers believed it worked, but it was producing garbage data. I checked it with Agilent-ADS, and real life components many times. In V.4 it was crippled.
Was it fixed in V.5?
