ev B1 Description of Measured Specifications Parameter Description VSW Voltage standing wave ra.o, the impedance match to 50Ω, the ideal value is 1:1. eturn Loss Loss of signal power resul.ng from the reflec.on caused by discon.nuity of transmission line. Insertion Loss The input power divided by sum of power at the coupling port & transmission port. Coupling The input power divided by the power at coupling port. Transmission The input power divided by the power at transmission port. Directivity The power at the coupling port divided by the power at the isolated. Test Method 1. Calibrating your vector network analyzer. 2. Connect the VNA 4 Port to DUT respectively. 3. Measure the data of coupling through port 1 to port 4(S41). 4. Measure the data of transmission through port 1 to port 2(S21). 5. Measure the data of isolation through port 1 to port 3(S31). 6. Measure the data of return loss port 1, port 2, port 3 & port 4. 7.
