The Agilent 85135E is a 97.2 cm (38.25 in) long¹ flexible cable with a 2.4 mm female² to 7 mm connector. Cable frequency range is dc to 18 GHz with a return loss of 17 dB or better. Insertion loss is 0.46 * sqrt (f) + 0.3, where f is frequency in GHz, for the test port connector and 2.25 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 85135E is less than 0.22 dB and phase is 0.16*f + 0.8, 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.
