ABSTRACT:
A system for measuring performance of a serial communications link includes a system under test including at least one transmitter and at least one receiver coupled together via a serial data communications link, wherein at least one of the transmitter and the receiver has at least one tunable parameter, at least one controller coupled to at least one of a transmitter and a receiver via a joint test action group JTAG interface, and logic configured to perform a bit error ratio test (BERT) at a plurality of receiver phase locations over a defined time period and concluding the BERT for a particular phase location if a BERT error count is greater than 0 at the particular phase location.
