– Key Features
The assembly incorporates NMD connectors with oversized coupling threads for enhanced mechanical stability at the network analyzer test port. The PSC connector end provides precision slotless construction for improved electrical repeatability and connector durability. The flexible cable design accommodates tight routing while maintaining a 2.5-inch minimum bend radius to preserve phase stability during 90-degree bends.
The center conductor requires careful handling to prevent damage from excessive stretching, tight coiling, or repeated bending cycles. ESD protection is mandatory during connector handling, inspection, and cleaning on static-sensitive circuits.
– Typical Applications
Test port extension for Keysight network analyzers with male NMD-2.4 mm test ports. Suitable for S-parameter measurements, component characterization, and calibration applications spanning DC through 50 GHz.
– Compatibility & Integration
Designed specifically for Keysight network analyzers featuring male NMD-2.4 mm test ports. The rugged female NMD connector mates only with standard network analyzer test ports; it does not interface with conventional male 2.4 mm connectors. The opposite end offers PSC connector configuration for device under test connections.
