The Agilent 85133C is an 81 cm (32 in) long semi-rigid cable with a 2.4 mm female to PSC-2.4 mm female connector. Cable frequency range is dc to 50 GHz with a return loss of 15 dB or better. Insertion loss is 0.84 * sqrt (f) + 0.3, where f is frequency in GHz, for the test port connector and 5.6 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 Agilent 85133C is is less than 0.06 dB and phase is 0.18*f, where f is frequency in GHz.
