An alien cross-talk method involves a victim cable and one or more disturber cables. The method encompasses a transmission of a RF test signal on each disturber cable between an alien cross-talk test signal unit connected to one end of a disturber cable and another alien cross-talk test signal unit connected to the other end of the disturber cable. The method further involves a measurement of an alien cross-talk signal generated on the victim cable in response to each cross-talk coupling of the victim cable and the disturber cable(s) based on the transmission of the RF test signal(s) on the disturber cable(s). The RF test signal(s) can be in the form of a RF frequency sweep and the measurement of the alien cross-talk signal can involve an execution of a RF frequency measurement sweep for acquiring samples of the alien cross-talk signal generated on the victim cable.

Test system and method for field measurement of alien cross-talk

According to an aspect of the invention, a method for determining near-end cross-talk effects is provided. A periodic test signal having a frequency increasing in predetermined steps is input into a conductor of a transmission cable. A raw cross-talk signal is received from another conductor of the transmission cable and the received cross-talk signal is processed in the frequency domain to determine a combination of near-end cross-talk components of the received cross-talk signal. The combination of near-end cross-talk components represents the characteristic of the near-end cross-talk effects.
