Доброго дня, Виктор!
Если смотреть мануал:
"S11 Magical. S11 and VSWR can be used to characterize the antenna or RF circuit
matching degree. But the S11 have some of the features of its own. Such as measuring the
loss of the cable, is generally used S21, namely vector network analyzer or scanner to
measure the two ports, in fact, use a single port impedance analyzer can also be measured. A
cable connected to our RF impedance analyzer port, the other end open. Then read S11
divided by 2, that is, this RF cable loss, of course, would be accurate to low frequency, high
frequency, then the frequency fluctuates with the change, it is best to use the sweep function,
adjacent The maximum and minimum mean it."
Но я эти строки просто пока игнорирую.
Более важно то, что выше.
