Excellent point. Is there a tag between the analyzer sweep range and its resolution BW? I should do a cal over a reasonable narrow frequency range and see if this helps the situation. Otherwise it may very well be RBW limited.

it's not that surprising, I think, considering that the RBW (or IF BW) of this instrument is definitely not
narrow enough to give you the resolution required for like a 1KHz or perhaps even 5KHz span. of course number of sample points is another bottleneck
but not as critical as the RBW.
Does anybody know what the RBW actually is?
