HP5343A N-Connector for Microwave Input

Question asked by kbuehler on Nov 2, 2012
I got a used 5343A in decent condition. Initially, its power-supply was broken. Filter capacitors on line input were dead. Replaced them, now counter works again.

The only thing I am still missing is the N-connector outer half of the microwave input. Seems to me it is a fused connector, similar to the BNC-Type on direct input.

The ref&service manual does not even mention it. The BNC-connector is explained in detail. Even a drawing is provided. But nothing about the N-connector at the microwave-input. Since I assume that similar connectors are used until today to protect input amps, can anyone provide me with some information, part number, drawing, replacement info.
