Hi,
I just got a Tek 491 10MHz-40GHz spectrum analyzer (40GHz with external mixer) for USD110 on EBay. It was claimed to be working, but Band B (275MHz-2GHz) has a missing part, which is most probably a N to ? connector converter. However, due to my lack of experience in RF, I have no idea what the connector is called, so can anyone please enlighten me on what the connector is, and even better, tell me how to get a N to ? adaptor? Thanks! (bonus teardown attached).
Best regards,
QuantumPhys
