Cable frequency range: DC to 18 GHz with a return loss of 17 dB or better
Insertion loss is 0.3 sqrt (f) + 0.2, 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 Agilent 85135F is less than 0.12 dB and phase is 0.13 f + 0.5, where f is frquency in GHz
