Achieve phase stability with these 53-cm cables when a DUT is connected between cable ends


The Keysight 85131D is an 53 cm (21 in) long1 semi-rigid cable set composed of a 3.5 mm female2 to PSC-3.5 mm female connector and a 3.5 mm female2 to 3.5 mm 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 * sqrt(f) + 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 Keysight 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.
