The Keysight 85131H is a 62.2 cm (24.5 in) long1 flexible cable with a 3.5 mm female2 to 3.5 mm male connector. Cable frequency range is dc to 26.5 GHz with a return loss greater than or equal to 16 dB. Insertion loss is 0.25 * sqrt (f) + 0.2 dB (where f is frequency is GHz) for the test port connector, and 1.5 dB at maximum frequency for the device connector. Phase stability of semi-rigid/flexible cables is characterized with a 90 degree bend using a 3 inch radius. Stability1 of the Keysight 85131H is less than 0.12 dB and phase is 0.13o * f + 0.5o, (where f is frequency in GHz).
1Â Cable length and stability are supplemental characteristics.
2Â Special rugged female connecter is designed specifically for connecting to the network analyzer test port, but does not mate with a standard male connector.
