What is an NMD connector?

The NMD connector is a ruggedized test-port connector used on network analyzers. Most often, the connectors used are 3.5mm, 2.9mm, 2.4mm male, and 1.85mm connectors. These connectors include a large threaded body that is specially designed to stabilize the test port cable when attached to the front of the analyzer or test set using MegaPhase test port cables. The design of these connectors allows the use of standard female 3.5mm, 2.4mm, 2.9mm and 1.85mm cables and adapters. Since the test port connectors are male connectors, they have standard inside threads that can accomodate these female connectors. It is best to use the recommended cables with NMD connector. NMD stands for Network Measurements Division, an outdated term for the original HP division that produced the Agilent 8510A and 8720A analyzers.
