The Keysight 85135C is a single 81 cm (32 in) long1 semi-rigid cable with a 2.4 mm female2 to 7 mm connector. Cable frequency range is dc to 18 GHz with a return loss of 17 dB or better. Insertion loss is 0.46 * sqrt (f) + 0.3, where f is frequency in GHz, for the test port connector and 2.25 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 Keysight 85135C is less than 0.06 dB and phase is 0.18*f, 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.
