I'm working on a conducted interference test plan. I have one interferer network and one victim network as shown in the attached schematic. Each network has two transceivers. Transceivers belonging to the same network should exchange data frames. All these transceivers are interconnected using cables through splitters/combiners (rather than over the air) to exchange data. Interferer network is introducing interference to the victim DUT.
My question is would the splitters/combiners work for this application? In other words are they full duplex devices that can transfer signal bi-directionally? Also what would happen if a splitter/combiner (C1) has signal on both its sum port (Ps) and one of its input ports (P3)? Would that create a problem for other input/output ports (P3). Thanks for the help.
P. S. I'm using mini-circuits ZN4PD1-63+ combiner/splitter.
