Cross Voltage
Crossing percentage is a
measure of the amplitude
of the crossing points
relative to the 1 level and 0
level.
Note: The Cross Voltage is
calculated according to
the BER Threshold set in
the BERT from Calculate
Measurement Parameters
of the View Tab.
12
Signal to Noise Ratio
In signal-to-noise, the
"signal" is the information
power of the signal
indicated by the difference
between the ‘1’, and ‘0’
level. The "noise" is the
combined standard
deviations of the ‘1’ level
spread, and the ‘0’ level
spread.
13
Extiction Ratio
Extinction ratio is the ratio
of the 1 level power and the
0 level power of an eye
diagram.
Note: The Extinction Ratio
is calculated using the
Dark Level and Conversion
Gain of the View Tab.
14
OMA
The Optical Modulation
Amplitude (OMA) is the
difference between the 1-
level power and 0-level
power.
Note: The OMA is
calculated using the Dark
Level and Conversion Gain
of the View Tab.
