Which of the following can be measured with a vector network analyzer?
- A.Input impedance
- B.Output impedance
- C.Reflection coefficient
- D.All these choices are correct (correct answer)
WhyA vector network analyzer can measure input impedance, output impedance, and reflection coefficient. A vector network analyzer can measure input impedance, output impedance, and reflection coefficient, all of which come directly out of the same underlying S-parameter measurements a VNA performs, answer D. Since it genuinely measures all three, no single one alone is the complete answer.
