Features:

The Keysight 85131C is an 81 cm (32 in) long1 semi-rigid cable with a 3.5 mm female2-to-PSC-3.5 mm female connector. Cable frequency range is DC to 26.5 GHz with a return loss of 17 dB or better. Insertion loss is 0.43 * sqrt(f) + 0.3, where f is frequency in gigahertz, for the test port connector and 2.5 dB at maximum frequency for the device connector. Phase stability of the semi-rigid / flexible cables is specified with a 90-degree bend using a 4 to 3-inch radius. Stability1 of the 85131C is less than 0.06 dB, and phase is 0.16 * f + 0.5, where f is frequency in gigahertz.

1 Cable length and stability are supplemental characteristics.

2 Special rugged female connector links to the network analyzer test port but does not mate with a standard male connector.
