The demand for high data rates in MOST systems is driven by automotive applications like high resolution video entertainment and driver assistance systems with uncompressed video signals. As data rates increase, so does the complexity of the physical challenges. Unfortunately, this increase is not linear. In addition, cost issues limit the characteristics of the transport channel. In order to find a good balance between these different design targets, it is important to determine the right transport method – for example NRZ or PAM4 –, redundancy of the physical layer such as 8 bit/10 bit coding, and equalisation for the transmitter (pre/de-emphasis) and/or receiver (FFE/DFE).

Repeatability and accuracy of compliance verification methods are important for detecting the limitations of a design and the reliability of the implemented transmission technology. Based on these results, the decision might be made to start with a re-design of the tested components, which certainly has an impact on development cost and time to market for the final product. Therefore, the accuracy of these tests results is critical.
