Automatic measurements on communications signals
NOTE. If a standard listed in this manual is not available on your instrument, it is because the configuration or bandwidth of
your instrument cannot test that standard.
Although this oscilloscope is not a calibrated optical reference receiver, you can use it with mask testing to evaluate general
optical signal characteristics and wave shape, using an external O/ E converter.

Levels used in taking eye measurements
All eye-diagram measurements are based on the power level, the voltage level, or the time locations of edges within each
acquisition.
The next figure shows the areas of an eye-diagram used to calculate measurements.
P values. The P values include the mean and standard deviation of the vertical location of PTop and PBase. These areas are
used with a specified sample size to statistically measure the following values
1
:
■
PTop Mean. This is the mean value of PTop.
■
PTop Sigma. This is the standard deviation of PTop.
■
PBase Mean. This is the mean value of PBase within the Eye Aperture.
■
PBase Sigma. This is the standard deviation of PBase within the Eye Aperture.
