Hi:

I remember from working on the 8410/8409 that sweepers are bad news for 
VNAs.  The problem is both repeatability of frequency (you need to come 
back to the same frequency many times then combine all that data for 
calibration and for measurement) and phase noise.  You really need a 
synthesized source.
