There are actually two traces shown on the VNA. One is stored in memory.
It is so close to the zero line you can barely see it, but if you look at
the far right, near 7 GHz, you can just see it dipping below zero due to
its loss.
I forgot to say, the trace that¡¯s barely visible is the thru on the left of
the photograph. It¡¯s return loss is very close to 0 dB even at 7 GHz.
