One level: The mean value of the logical one level of the eye diagram. Bit period: ... BER is the number of bit errors encountered divided by the total number of bits transmitted. The ratio is ...

On an oscilloscope's eye-pattern diagram, the distance between peak deterministic and random jitter amplitudes (the unit interval, or UI) is often called a "bathtub," which functions as a bit ...

An NRZ eye diagram contains a single eye, while a PAM-4 eye diagram has three vertical eyes. ... Anritsuâ s MP1800A performs bit-error-rate tests from 0.1 Gbit/s to 32.1 Gbit/s; ...

Today's methods for BER (bit-error-rate) testing of high-speed serial links such as PCIe and SATA rely on predetermined patterns that don't. ... The jitter added to the system shrinks the openings in ...
