The high speed PAM4 signals with repeating data pattern can be analyzed and measured on the equivalent-time sampling oscilloscopes. The harmonics not synchronous with the data pattern are aliased. The aliasing is analyzed, and a method is described to remove the unwanted aliased harmonics.The real-time oscilloscopes have the real-time sample rate high enough to prevent aliasing. A numerical example is given that compares the TDECQ measurement on the sampling scope and on the real-time scopes.
When comparing the measurement results between equivalent time sampling oscilloscopes and real-time oscilloscopes, it is required to consider that the components not correlated to data pattern can be aliased on the equivalent time sampling scope. Appropriate steps can be taken to improve the correlation between the two types of oscilloscopes.
