ABSTRACT:
The present invention is a system and method that uses a digital spectrum analyzer to digitize a spectrum and loads the digitized spectrum into a computer. The computer scans the spectrum to determine a zero dB reference by cyclic averaging and determines the upper and lower cutoff frequencies using inward and outward scan techniques which are averaged. During zero dB level determination holes in the spectrum are ignored and during upper and lower cutoff frequency determination the holes or drop outs in the spectrum are located, counted and characterized.
