– Typical Applications
Precision network analyzer measurements requiring stable, repeatable performance to 50 GHz. Metrology-grade characterization where connector repeatability and phase stability are critical.
– Compatibility & Integration
Designed for Keysight network analyzers equipped with male NMD-2.4 mm test ports. The ruggedized female NMD connector at the test port end is not compatible with standard male connectors. PSC connectors on the device end ensure optimal performance with precision slotless mating interfaces.
