Ideally, yes.? But finding a VNA that costs less than $500 that has the dynamic range and sweep speed to do so real-time does not appear to be currently available.? My main point was that there are still some scalar measurements where having a tracking generator might allow you to make S21 measurements that the current crop of NanoVNA and LiteVNA's cannot perform as well.

Again, I have not read the full article, so I don't know what dynamic range the author's build is capable of achieving.
