Outline
SNR (Signal to Noise Ratio)
This is the ratio of the signal amplitude to the noise amplitude.
The sampling oscilloscope can be calculated by the following formula.
SNR= (1 Level–0 Level)/(
1
+
0
)
1
: 1 Level Standard Deviation
0
: 0 Level Standard Deviation
Eye Crossing Percentage
The Eye Crossing Percentage is the ratio of the Eye amplitude rising and
falling waveforms. The calculation formula is as follows. Refer to Figure
1.5-1.
Crossing = (crossing point level–0 Level)/(1 Level–0 Level)
Eye Amplitude
The eye amplitude is the difference between 1 Level and 0 Level. Refer to
Figure 1.5-1.
Eye Height
The eye height can be calculated by the following formula. Refer to Figure
1.5-1.
Eye Height = (1 Level–3
1
) – (0 Level +3
0
)
1
: 1 Level Standard Deviation
0
: 0 Level Standard Deviation
