26.5 GHz Test Port Return Cables
Keysight 85131FThe Keysight 85131F is a 62.2 cm (24.5 in) long flexible cable set composed of a 3.5 mm female to PSC-3.5 mm female connector and a 3.5 mm female to a 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 in 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 specified with a 90 degree bend using a 4 to 3 inch radius. Stability of the Keysight 85131F is less than 0.12 dB and phase is 0.13 * 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.
