AORM Software Package

923133 Rev A ISSUED: June 2013 101

The AORM package histograms the values inside each pit to determine the most likely amplitude:

the most densely populated region.

The next figure shows the histogram of the pits’ amplitudes. It is easily seen that the most likely

amplitude is approximately 32 mV (exactly 31.9 mV). The top is calculated by averaging all of the

waveform data points at or above this, to give a result of 32.89 mV.

In the next figure, the top bisects the two flattest regions at the top of the waveform and, in effect,

calculates the value that would be estimated from examination of an eye-pattern persistence

map.
