Hello all,
I've recently bought the FPC1500 fully loaded version and was excited to take the first measurements.
First I tried TG measurement and 50R terminator.
I was a bit surprised since I didn't get the expected result (instead around -9.5db I got -3.5db)
After that, I've tried Smith chart measurement and I've got this:
a) S11 measurement using 50R terminator
Dot is on "1" as expected
b) S11 measurement of RF input port
Of course, I understand the parasitic components of the cable and N-type to SMA adapter but should it be THAT bad?
