RE: XAUI SJ jitter test
Boaz,
I can comment that for the system we have in our lab there is a 10MHz FM
modulation bandwidth for the clock source and a 20Mhz limit for the
modulation source. I am not aware of what the limit is for the Pattern
generator itself.

Shawn,
The BERT is the problem or it is the Pattern Generator/Signal Generator?

Tom, I'm asking you this as I seem to recall from the Jan Interim you
presented on the Annex 48A jitter test approach. If I am in error please
forgive me.
In D2.1, Clause 47, Page 285, Figure 47-8 shows Sinusoidal Jitter
Tolerance Mask that requires 0.1UI SJ tolerance up to 20Mhz. Can you or
anyone on the reflector describe how this limit can be tested. I am told
that the HP 3G and 12G BERTs can only modulate up to 10Mhz.
Regards,
Shawn Rogers
