Data Management with Spectrum Analyzers

Abstract

A spectrum analyzer contains a number of improvements that adapt it to common commercial uses. The spectrum analyzer is capable of automatically wirelessly receiving and synchronizing frequency spectrum data collected from multiple remote spectrum analyzers with respect to frequency, time and location. A selector function is used to create composite fre quency data set from multiple frequency data sets while allowing retroactive identification and examination of the original frequency data. An improved non-linear graphical display of the frequency spectrum data is created by automatically expanding the resolution of frequency axis for frequency ranges having signals of interest and contracting the resolution of the frequency axis of frequency ranges having no signals of interest.

What is claimed is: 
     
         1 . A method of displaying collected spectrum analyzer data, said method comprising:
 identifying a frequency spectrum span from the spectrum analyzer data;   identifying frequency ranges in said identified frequency span having a high concentration of signals; and   producing an output graphical display having a frequency axis wherein frequency ranges having a high concentration of signals are graphically expanded and displayed while frequency ranges having a lower concentration of signals are graphically condensed.
