– Compatibility & Integration

Designed specifically for Keysight network analyzers with male NMD-2.4 mm test ports. The NMD-2.4 mm female connector is tailored for analyzer test ports and will not mate with standard male connectors. The PSC-3.5 mm connector mates with standard 3.5 mm connectors; 2.4 mm connectors accommodate SMA, 3.5 mm, and 2.92 mm adapters with precision adapters.
