The delay skew test is used to find the difference in propagation delay between the fastest and slowest set of wire pairs. An ideal skew is between 25 and 50 nanoseconds over a 100-meter cable. The lower this skew the better; less than 25 ns is excellent, but 45 to 50 ns is marginal.
Fluke Corporation is an American manufacturer of industrial test, measurement, and diagnostic equipment, including electronic test equipment. It was started in 1948 by John Fluke while he was employed at General Electric .
A cable tester is an electronic device used to verify the electrical connections in a signal cable or other wired assembly. Basic cable testers are continuity testers that verify the existence of a conductive path between ends of the cable, and verify the correct wiring of connectors on the cable. More advanced cable testers can measure the ...

The on-test failure rates on a cable system are in the range of 0.2 to 4% for 30 min tests performed at the IEEE 400.2 voltage levels. IEEE Std. 400.2 provides suggested time and voltage test levels but exact parameters are not possible since defect growth rates are not known and can vary widely.
Murray loop test employs the principle of wheatstone bridge for locating the fault. To perform this test, it is necessary to have a sound cable running alongside the faulty cable. One end of the faulted cable is connected through a pair of resistors to the voltage source. Also a null detector is connected. The other end of the cable is shorted.
Test Manager deals with planning and control of the test process. Test Analyst concerns, among other things, reviews and black box testing methods. Technical Test Analyst includes component tests (also called unit test), requiring knowledge of white box testing and non-functional testing methods – this section also includes test tools.
In fixture testing, while ICT fixtures test each individual component on a PCB, functional test fixtures assess the entire board's functionality by applying power and verifying that the system operates correctly. [6] Types Functional testing includes but is not limited to: [1] Sanity testing, a.k.a. smoke testing; Regression testing; Usability ...
