NO RATINGS
? why you recommend don't use smooth funciton average function

 

ans:  If you use 1kHz IF BW or lower, have a good low noise VNA like ZVA-40 you do not need it, and it masks resonance in systems.   Some VNA's store the touchstone with S-parameter smoothing which creates problems.    You can post process smooth using Matlab very eaisly.   I only smooth group delay btw.   Have a plot of this in day 3 I believe.
