Using N9320B to measure frequency;
Setup: Freq = XXXXMHz
file = /tffs0/file/AAA.STA
I am experiencing measurements that have approx. 30KHz of uncaptured signal, i.e. the captured spectrum has power levels of -50dBm or greater for nearly the entire sweep, EXCEPT for a 30KHz area that is nearly noise floor level. It appears to be random areas of the screen. If it occurs during an automatic (remote) reading, I have received a peak search reading outside the allowable limits of my frequency tolerance. When the software desires to print the captured signal, it has the low signal as previously described.
