Using an E5071C VNA with 2 ports (300KHz. To 8.5GHz.)(50 ohm). Looking to use a E5091A (9 port)
My question is, if you drive the E5091A with only a 2 port NWA on the inputs rather than a 4 port as all the literature suggests one need to do? Do you still get 9 ports or only halve the amount of ports?
I don't have an ENA myself so I can't remember right now if the ENA's user interface allows for the possibility of controlling the port switching for ports R1+, R2+, R3+, R1-, R2- and R3- of the E5091A (those are its output ports which switch only to its Port 3 and Port 4 input ports) when your ENA is a 2-port model. If it can do that, then if you wire your ENA's ports to Ports 3 and 4 of that testset, you'd get effectively 6 total ports. Otherwise, since Ports 1 and 2 of that testset can only switch to its A, T1 and T2 output ports, then you'd only get 3 total ports if you'd have to use those two input ports.
