I had started a thread about how to terminate a 75Ohm transmission line....The answer is in that older thread already. You can build an "ideal" test fixture with perfect transmission lines at 75ohm and then de-embed the cables and fixture when you measure the DUT. Its easier when the VNA automates this for you but its still possible to do manually if you can't afford the modern tools, and design of the test fixtures allows you to balance the important characteristics for your application.
As I said, this is new territory - so speak slowly
