I use the LiteVNA to measure the input impendance of tinysa ultra,but the results is strange:the SWR is too high,means the input impendance isn't 50Ohm
I set the sa as 30db attenuate,0db attenuate and enable LNA,then I measured these three states separately,and the all the results showed the SWR was very high
I think it's abnormal,is it any problem?
?
