The Keysight 85130D Test Port Adapter Set protects network analyzer test ports during direct connection to devices under test. This two-piece adapter set bridges the analyzer’s rugged test port to standard 3.5 mm connectors, enabling seamless integration with DUT interfaces while maintaining signal integrity across microwave frequencies.
Technical Specifications
• Frequency Range: DC to 26.5 GHz
• Return Loss: 28 dB or better
• Weight: 2.3 lbs
• Dimensions: 6 × 6 × 6 inches
– Key Features
The kit comprises two adapters: a 3.5 mm to PSC-3.5 mm male adapter and a 3.5 mm to PSC-3.5 mm female adapter. The test port side incorporates a special rugged female connector engineered specifically for network analyzer test ports—this connector design is not compatible with standard male connectors, preventing incorrect mating and protecting both the analyzer and adapter from damage.
The DUT-facing side provides standard 3.5 mm connectors, allowing connection to commercial test fixtures and measurement setups without modification.
– Typical Applications
This adapter set is intended for RF and microwave component testing where network analyzer test ports require mechanical protection and interface standardization. It accommodates measurement scenarios ranging from DC through 26.5 GHz, covering applications in component characterization, transmission line analysis, and filter testing.
– Compatibility & Integration
The 85130D adapter set integrates with Keysight network analyzers equipped with ruggedized test ports. The asymmetric connector design on the analyzer side ensures proper orientation and prevents accidental connection of incompatible hardware. DUT interfaces accept standard 3.5 mm male or female connectors, making the adapters suitable for most commercial test equipment configurations.
Each kit includes an Operating and Service Manual detailing contents, specifications, performance verification procedures, replaceable parts, and associated equipment requirements.
