Signal Integrity testing

For a communication device, testing the quality of the signals output from the device, and signals that have been input at interfaces will detect signal integrity problems.

Application Note: Jitter Analysis

Output Jitter (Jitter Generation) The amount of jitter generated by the Device Under Test (DUT) is called the Output Jitter (Jitter Generation). The ITU-T, which regulates standards such as SONET/SDH in

APPLICATION NOTE

Each standard applies to a particular purpose in a unique signal integrity environment. For example, Table 1 shows separate specifications for cables, backplanes, and both SM and MM fiber optics.
