Manufacturer's Description

The Keysight (Agilent) 85131D is a Semi-Rigid Cable Set providing a 3.5 mm (Test Port) to 3.5 mm interface, designed to achieve phase stability when a device under test (DUT) is connected between cable ends. The set is composed of two cables: a 3.5 mm female to PSC-3.5 mm female cable, and a 3.5 mm female to 3.5 mm male cable. The ruggedised female (PSC) connector on the test port side is designed specifically for direct connection to compatible Keysight/Agilent 3.5 mm network analyser test ports (such as those on the 8514B, 8515A, and 85110A test sets) and cannot be mated with standard 3.5 mm male connectors. Typical applications include S-parameter measurements, component characterisation, and calibration verification across RF and microwave frequencies up to 26.5 GHz.
