Hello Everyone,
I am trying to find out S21 using NI 2901 SDR. I am interested in Magnitude and Angle of S21.
Firstly, I am transmitting a signal from TX1. Using Power splitter at TX1, I am splitting Input and sending it back to RX1 for reference for S21. At RX2, I am receiving a signal transmitted from the TX antenna. After the collection of signals, by simply dividing the RX2 signal by the RX1 signal, I am getting S21. Is this the correct way? further, how can I do phase calibration of TX and RX? Attached is the working diagram. Kindly suggest VI which will be helpful.
Regards. Thanks in Advance
