I am devoloping a software on MATLAB platform to test antenna using VNA in the degree college.Interfacing VNA was not a problem.I could able get the center frequency of the antenna by measuring S11 parameter

 

Now I want to measure the S21 parameter at the single center frequency.Actually I want to mesure the power radiated by the horn antenna at port1 by the recieving horn in port2.Iwill rotate the recieving antenna to get power at different angle to get the antenna field pattern.

 

Can any one tell me what are the VNA specific command I can use to achieve the above task.The model of VNA in my college lab is 8722ES
