ABSTRACT:
Methods and apparatus for evaluating the performance of electronic components and systems by minimizing or eliminating intersymbol interference (ISI). The apparatus includes a transmitter, a device under test, a receiver, and at least one electrical connection between the transmitter and receiver that bypasses the device under test. The electrical connection between the transmitter and receiver transmits information characterizing the intersymbol interference of the transmitted signal to the receiver. The receiver includes an equalizer that uses the information characterizing the intersymbol interference of the transmitted signal to minimize or eliminate intersymbol interference in the received signal wherein the distortion introduced by the device under test can be isolated and characterized. The methods and devices can be used to evaluate the performance of data transmission systems and components, for example, software models of high-speed data transmission systems, and, among other things, reduces the need for fabricating prototype hardware for testing.
