In the eye diagram test, the software clock recovery (CDR) technology pioneered by LeCroy has become the industry standard. In today's era of high-speed serial buses, oscilloscopes are required to have stronger data processing capabilities to perform real-time eye diagram analysis on a large number of data samples. For example, the eye diagram analysis of PCIE-G2 requires the measurement of 1 million UI data at a time. Not all manufacturers' oscilloscopes can perform real-time and dynamic eye diagram measurements on all captured data samples like LeCroy oscilloscopes.
