The Maury Microwave 7909A1 is a precision NMD2.4mm test port adapter engineered to protect VNA test ports from wear while maintaining signal integrity across RF and microwave frequencies. It connects NMD-style 2.4mm male test ports—found on Agilent, Keysight, Rhode & Schwarz, and Anritsu VNA platforms—to standard 2.4mm female connectors. By absorbing mechanical stress at the connection interface, the 7909A1 extends VNA test port life and reduces downtime from costly repairs.
