...HP8593E phase noise intermittent problem

I have a problem on my 8593A spectrum.  In a SPAN smaller then 100 KHz, I can see that the phase noise is increasing sporadically.  Its look like phase noise hit on the VCO, like the DC supply of the YIG is not so clean.
Is somebody could tell me where to look?  Is it worth for me to investigate or there is no hope?

Thank you
