To adjust diplexers,?duplexers filters?etc better off using a VNA. A spectrum analyzer / tracking generator only provides amplitude, a VNA measures S parameters i.e. amplitude?and?phase etc. Always terminate all unconnected ports of a DUT.? ?

I can hardly imagine the need to get another ten dB of dynamic range beyond the 80 dB available from the litevna.
? I just checked my litevna and above 3.5Gz you don't get anywhere near 80 dB of dynamic range.? I haven't read the full article but for tuning duplexers a tracking generator could be a handy accessory.
