[time-nuts] 5370A jitter - What to look for

I need to fix my HP 5370A jitter to reduce it to something reasonable.
It is now about 3 nano seconds and is partially periodic. It is not 
totally random
If I plot the data (using plotter) I see what looks like two oscillators 
beating against
each other with superimposed jitter

Wondering if that has a known source or do have to find the problem my 
self :-)
I do not have the two matched cables and the pulse generator to do the 
complete alignment.
I do have a spectrum analyzer to do the 200 MHz. alignment

I can send the data file if that is permitted.
