A cable testing device apparatus has been developed so as to measure the NEXT and ELFEXT characteristics of a cable containing a plurality of twisted pairs. In particular, the present invention simultaneously provides each twisted pair within the cable with an electrical signal of equal magnitude and measuring the equivalent power sum output for each of the individual twisted pairs within the cable. Thus, a total of 25 measurements for each test are needed, for a total of 50 tests.
