An alien cross-talking testing system employs a plurality of alien cross-talk test signal units, an alien cross-talk measurement unit and an interconnection base unit. Each alien cross-talk test signal unit is in electrical communication with a different disturber cable to participate in a transmission of a RF test signal thereon. The alien cross-talk measurement unit is in electrical communication with a victim cable to measure an alien cross-talk signal generated on the victim cable in response to any alien cross-talk coupling between the victim cable and one or more of the disturber cables. The interconnection base unit is in electrical communication with the alien cross-talk measurement unit and the plurality of alien cross-talk test signals units to control non-simultaneous transmissions by the plurality of alien cross-talk test signal units of the RF test signals at a same frequency on the disturber cables as commanded by the alien cross-talk measurement unit.
