The Agilent 85131E is a 96.5cm (38 inches) long1 flexible cable with a 3.5mm female2 to PSC-3.5mm (female) connector. Cable frequency range is DC to 26.5 GHz with a return loss greater or equal to 16 dB. Insertion loss is 0.35*(f/2) + 0.3, where f is frequency in GHz, for the test port connector and 2.1 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 85131E is less than 0.22 dB and phase is 0.16*f + 0.8, 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.
