Abstract:

Spectrum analyzers are commonly used in random signal analysis to locate discrete sine wave components in a broadband noise background. The report describes a procedure for determining the sensitivity of practical spectrum analyzers for this task. The minimum detectable signal level for an idealized system is first computed and then adjusted to account for deviations from ideal behavior in a practical system. It is felt that the result allows prediction of sensitivity within about 0.5 decibels.
