ABSTRACT:
Test pulses representing bits combined in bursts are generated, defined in form and amplitude, and jittered, defined by reading curve shaped characteristic data and jitter identification data from digital memories, for the purpose of simulating defined cable types and lengths and are transmitted to a unit to be tested. In a receiver, the test pulse is received and forwarded by the unit under test are accepted for the purpose of a test and are compared to the test pulses transmitted by the transmitter.
