Many digital-communications systems use non-return-to-zero (NRZ) signaling, and system designers have created many NRZ test patterns to test and verify their products. These patterns usually either ...

As pointed out in the comments section of my previous blog post, Tx BER testing can only go so far in predicting the BER of a system. For rigorous Rx testing, a PG ...

Both synchronous and asynchronous wide area networks (WANs)can be tested at speeds in excess of 10 Mb/s with the one-pound, Model 78 Bit Error Rate Test Set (BERT ...

is often called a "bathtub," which functions as a bit-error-rate (BER) indicator (... Typical communications applications usually seek a BER of about 1 × 10-12. The eye pattern is formed by ...
