I recently made a video showing how to measure impedance 3 ways with a
VNA including the s11, series sw1, and the shunt s21 methods.
See if interested.

Larry I just watched your video and it does a good job of explaining the three methods. If you are interested in doing a follow-on it would be interesting to see the following:
1. Comparison between SimSmith and NanoVNA using test components on the nanoVNA
2. Investigate what happens as you introduce deviation into the ideal CH0 and CH1 50 ohm impedance as Kurt Poulson discussed above.
Maybe we should move this discussion to a new post so the topic does not get buried in the discussion of 49:1 UN-UN testing.
