METHOD OF TERMINATING UNUSED PORTS DURING CROSSTALK MEASUREMENT
Methods for measuring crosstalk in an electronic circuit having multiple ports comprises determining two ports of interest of the electronic circuit, in which crosstalk will be measured between. Furthermore, the method includes determining one or more ports of the electronic circuit to be terminated, independent from the ports of interest, so that signals of these ports do not interfere with measuring crosstalk between the two ports of interest. To terminate the ports determined to be terminated, a piece of absorber sheet is used to cover the ports determined to be terminated. Pressure is applied to the piece of absorber sheet such that the piece of absorber sheet makes a good contact and absorbs signals traveling into the ports determined to be terminated, thereby terminating the ports determined to be terminated so that crosstalk between the two ports of interest may be effectively measured.
