The Agilent 85133H is a 63 cm (25 in) long flexible cable with a 2.4 mm female to 2.4 mm male connector. Cable frequency range is dc to 50 GHz with a return loss of greater than or equal to 15 dB. Insertion loss is less than 0.1 + 0.38* sqrt (f) + 0.017 f, (where f is frequency in GHz) for the test port connector and 3.64 dB at maximum frequency for the device connector. Phase stability of semi-rigid/flexile cables is characterized with a 90 degree bend using a 2.5 inch radius. Stabililty of the Agilent 85133H is less than 0.08 dB and phase is 0.08 f + 08 degrees (where f is frequency in GHz).
