How to Use Spectrum Analyzer for Noise Testing? Part 1

The spectrum analyzer is a powerful tool for making noise measurements. In general, spectrum analyzers can display the relation between power (or voltage) and frequency, which is similar to the noise spectral density curve. In fact, some spectrum analyzers have a special mode of operation that allows the measurement results to be displayed directly in spectral density units (ie nV/rt-Hz). In other cases, the measurement result must be multiplied by a correction factor to convert the relevant unit of measure into spectral density units.

spectrum analyzers, like oscilloscopes, are both digital and analog. One method of generating a spectral curve by an analog spectrum analyzer is to sweep a band-pass filter at various frequencies while plotting the measured output value of the filter. Another approach is to use superheterodyne reception, which performs scanning of the local oscillator at various frequencies. However, digital spectrum analyzers use fast Fourier transforms to generate the spectrum (often used with superheterodyne receiving technology).
