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=10xLog(pTopMean/pBaseMean)
Extinction Ratio Percent
Extinction ratio percent is the ratio of eye base to top expressed as a percentage. 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 Percent=100x(pTopMean/pBaseMean).
Eye Base
Eye Base is the base value used in the extinction ratio measurements.
Eye Base = pBaseMean
Eye diagram
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 x pTopSigma) - (pBaseMean + 3 x pBaseSigma)
Eye Top
Eye Top is the top value used in the extinction ratio measurements.
Eye Top = pTopMean.
