Tutorial 1: Measure Eye-Parameters

Example Extinction Ratio Measurement

10 Change the amount of data used for the histograms by pressing:

NUMBER SAMPLES and enter the # of samples

A larger value gives more accuracy, but increases the data acquisition time.

When making extinction ratio measurements in eyeline mode, the number

of samples should be increased from the default of 1000 to something on the

order of 20000 to insure a number of traces are evaluated to compute the

extinction ratio.

11 Clear the measured data from the screen by pressing:

OFF
