Simultaneous capturing pn data-values and spurs

I am having some trouble sending GPIB commands successfully to E502B. (I could successfully reset it but when I try to grab data etc., I am having some trouble. Need to learn a bit more before I can ask specific questions here)
Meanwhile I am trying to dump out phase noise and spurs using the GUI.
I am using segment phase noise as well as phase noise but I have the same trouble in both. How to capture spurs and phase noise data value at the same time instant.
Since I am using GUI, there is a significant lag in time in capturing phase noise using 'save-save data trace' and then pressing 'Trace-spurs-spurious list' . As a result, during post-processing of results, I see that I get peaks in phase noise where there is no data in spurious list and I get spur in spurious list where there is no peak in phase noise. I agree that this issue only arises when you have got moving spurs, but if your DUT is as it is, how to resolve this problem, can anybody help me.
Thanks and Regards,

FYI, I am using averge number of 16 and correlation number 32
