Method and apparatus for displaying eye diagram on an error performance analyzer

摘要

A method and apparatus for displaying an eye diagram on an error performance analyzer are disclosed. A first bit sequence is received and compared with a second bit sequence, the first bit sequence and the second bit sequence being substantially similar. For each delay increment for an entire clock period a bit error rate (BER) curve is constructed. The BER curve is then used to locate the bit voltage or bit voltage spread for the 0-bit and the 1-bit for a particular delay. This is repeated a predetermined number of times to cover an entire period. Then, the bit voltages or bit voltage spreads are displayed as an eye diagram.
