Wave Analyzer Dynamic Range and Bandwidth Requirements for Signal Noise Analysis.
Abstract
This paper first describes, in general terms, two techniques for measuring AM and FM noise that is close to the carrier frequency (near carrier-Doppler) of a radar or other microwave signal source. Either of these techniques produces outputs, in the frequency range from DC to a few hundred kilohertz, that must be further analyzed with an appropriate analyzer. The nature of the noise to be analyzed dictates limitations on the dynamic range and bandwidth of the instrument. These limitations are developed in this paper for the specific case described. However, this instrumentation problem and the solution described are broad enough in scope and tutorial enough in nature to be applicable to many video (audio band) noise analysis problems. A discussion of possible applications in the field of audio band signal analysis is presented. (Author)
