Duplexer setup = with two service monitors and a spectrum analyzer Can someone in the group give me a sketch diagram of the setup, for tuning a duplexer with the following equipment I have?. I have two (2) service monitors (Marconi 2955/A), and a spectrum analyzer (Avcom PSA-65A, no built-in tracking generator) Q...Will I be able to see the response graph of the duplexer, as when I use a spectrum analyzer with a built-in tracking generator? All comments will be appreciated, and set aside for the radio club here archive. v44kai.....Joel.
