Figure 7. Verification setup

Correct pattern length is determined by confirming that the tone spacing on

the spectrum analyzer equals (Output_Bit_Rate/(2

-1)), where n is the

specific pattern length. As an example, at 10 Gb/s the tone spacing for a

-1) pattern should be ~ 4.66 Hz (refer to Table 4 for tone spacings).
