If the data rate is 500 mbs, the maximum frequency is 250 mhz.
However, to get a good picture of the waveform, 3X or 5X or even 7X the
max frequency is required(odd harmonic content). 5X 250 would yield
1.25 Ghz and should give reasonable results.

> Your suggestions and comments would be greatly helpful.
