Thanks for the illustration. How did you get Q = 145.8? Why does the rectangular plot needs phase slope added to discern? Is the dip it too broad and shallow? A rectangular phase plot is available. How would you use it?
Alan, if I handed you a device and asked you to find the series-resonant frequency and the bandwidth at that point with a NanoVNA, what would you do? If the VNA was equipped with the feature you're proposing, what would you do differently?
