Since the reflector coefficient, Γ which shown in the VNA was in dB form. If I wanna look for the Zin by using the smith chart, I wonder is the Γ value is in normalize form or not. Can we directly apply the Γ in the smith chart to find the Zin?
Push the FORMAT button on your VNA front panel and change to Smith Chart. It's the easy way. Nevertheless, try to study harder before using a VNA (it's a very expensive toy to play with)
