2 port vector network analyzer
Hi all,
I want to test 2 parabolic dish (connected with feedhorn antenna) using 1 agilent vector network analyzer E5071B. I want to measure S11,S12,S21,S22. I have kept distance between the 2 dish about 1.5m. I am getting S11 and S22 about -12dB at the frequency between 2.3 to 2.4GHz. And S12 and S21 about -20dB.
I have a question.
1) Since I need to get the gain value in dBi, which value should I take? S11,S22,S12 or S21 to calculate.
2)How can I get an excel format graph from the S parameter images in the agilent vector network analyzer?
Plz reply me urgently.
Waiting for your reply. Very kind of you.
Thanx.
Regards,
Saran
