The Agilent/Keysight 85130A is a precision adapter kit that converts 3.5 mm test ports to a 7 mm interface for use with network analyzers. Designed for high-frequency measurements, this adapter set enables connection of 7 mm devices under test (DUT) to 3.5 mm test set ports while maintaining measurement accuracy and repeatability across demanding laboratory and production environments.
Technical Specifications
The 85130A comprises a set of precision special adapters with the following interface configuration:
• Test set end: 3.5 mm (female)
• DUT end: 7 mm
• Return loss: 28 dB or better
• Frequency range: Designed for high-frequency applications up to 26.5 GHz and beyond
– Key Features
• Precision construction maintains stable performance across wide frequency ranges
• Rugged design suitable for both laboratory and production use
• Accurate and repeatable measurements
• Finger-tightened connection recommended to avoid misalignment and connector damage
– Typical Applications
The 85130A serves network analyzer systems requiring port conversion. Careful connection practices prevent measurement errors caused by connector misalignment. When connecting, use clean foam swabs with isopropyl alcohol for connector maintenance; avoid abrasive materials.
– Compatibility & Integration
The 85130A is explicitly compatible with HP 8513A and 8515A test sets. When deployed with these test sets, the system requires HP 85132A or 85132B cables as test port return cables. This combination provides a complete adapter and cabling solution for precision RF measurements in the 3.5 mm to 7 mm conversion application.
