Abstract

The invention discloses a cable performance testing device and method and electronic equipment. The performance testing method comprises the following steps: acquiring a reference resistance value of a testing circuit; when the test circuit is connected with the to-be-tested cable, testing the to-be-tested cable according to a preset test task to obtain a test resistance value; and calculating the resistance value of the to-be-tested cable in the preset test task according to the reference resistance value and the test resistance value. According to the technical scheme, by adopting a comparison method of the reference resistance value and the test resistance value, the influence of the resistance of the test circuit on a test result is remarkably reduced, more accurate and reliable electrical characteristic measurement is provided especially in a performance test of a short cable, and the problem of errors in a traditional cable test method is solved.
