Review of procedures to overcome spurious effects in the measurement of RF communication cables29.10.2020
Given the large amount of parameters to be measured and calculated, data cable characterization is performed using fully automated test equipment (ATE). However, the obtained data strongly depend on the test setup, the calibration, the DUT preparation, and other parasitic effects. It is thus required to carry out some corrections on the basis of theoretical principles in order to extract the DUT intrinsic return loss and/or impedance. This paper presented at IWCS 2020 virtual conference describes various correction procedures to remove the influence of the operator in the cable preparation on the DUT characterization, as well as mismatch effects of cable fixtures.
