Extinction ratio
Extinction ratio is the ratio of eye top to base. This measurement is only valid when the acquisition mode is set to WfmDB,
FastAcq is enabled, or the measurement is taken on a reference waveform saved in FastAcq mode.
Ext Ratio=pTopMean/pBaseMean
Extinction ratio decibel
Extinction ratio decibel is the ratio of eye top to base expressed in decibels.
This measurement is only valid when the acquisition mode is set to WfmDB, FastAcq is enabled, or the measurement is taken on
a reference waveform saved in FastAcq mode.
ExtdB=10 × Log(pTopMean/pBaseMean)
Eye base
Eye Base is the base value used in the extinction ratio measurements.
Eye Base = pBaseMean
Eye diagram
The eye diagram is a synchronized display of a data stream that shows signal levels and transition regions, typically over one
cycle.
The eye diagram has the appearance of an opened eye. Compared to a normal instrument display, the eye diagram generally
appears as an untriggered waveform. This is because on successive cycles the signal is high and then low. The areas of interest
are the transition regions and eye opening.
Eye height
Eye height is the measurement of the eye height in volts.
Eye Height = (pTopMean - 3 × pTopSigma) - (pBaseMean + 3 × pBaseSigma)
