To measure Transfer impedance, Screening attenuation and the Coupling attenuation, the<br />
sample under test shall be matched with its characteristic impedance inside the matching case.<br />
In case of coaxial cable this is done easily with a Mini-Melf or comparable resistor, which is<br />
soldered between inner- and outer conductor. This task is much more difficult in case of<br />
balanced cables with four or more pairs.<br />
To match balanced pairs, the printed board contains two parallel mounted 50 Ohm mini<br />
resistors with one 25 Ohm mini resistor in series. This allows to match the common mode as<br />
well as the differential mode. The printed board is designed to fit into the contact case.<br />
