The Agilent 85131D is an 53cm (21 inches) long1 semi-rigid cable set composed of a 3.5mm female2 to PSC-3.5mm (female) connector and a 3.5mm female2 to 3.5mm (male) connector. Cable frequency range is DC to 26.5 GHz with a return loss of 16 dB or better. Insertion loss is 0.3*(f/2) + 0.2 dB, where f is frequency in GHz, for the test port connector and 1.8 dB at maximum frequency for the device connector. Phase stability of semi-rigid/flexible cables is specified with a 90-degree bend using a 4 to 3 inch radius. Stability1 of the Agilent 85131D is less than 0.06 dB and phase is 0.16* f + 0.5, where f is frequency in GHz.1 Cable length and stability are supplemental characteristics.2 Special rugged (female) connector is designed specifically for connecting to the network analyzer test port, but does not mate with a standard (male) connector.
