Agilent / Keysight 85133E Flexible Cable Set, 2.4 mm

The Agilent/Keysight 85133E Flexible Cable Set is a single-cable interconnect solution engineered for precision RF and microwave measurements from DC to 50 GHz. Terminated with NMD-2.4 mm female connectors on the test set end and PSC-2.4 mm female slotless connectors on the DUT end, this 97.2 cm cable delivers stable phase response and low insertion loss critical for vector network analysis. Metrology-grade Precision Slotless Connectors (PSC) provide a well-defined mechanical interface traceable to national measurement standards, significantly improving return loss measurement accuracy compared to conventional slotted designs.

– Key Features

• Single flexible cable optimized for direct DUT-to-test-port connection
• NMD connectors feature enlarged coupling threads for enhanced port stability
• PSC connectors eliminate slotting variability inherent in conventional designs
• Mechanical interface design is traceable to national measurement standards
• Maintains phase and magnitude stability through repeated flexing

– Compatibility & Integration

Designed for Keysight network analyzers equipped with male NMD-2.4 mm test ports. The rugged female NMD-2.4 mm connector on the test set end does not mate with standard male connectors.
