There are a wide variety of Signal/Spectrum Analyzers on the market that use a wide range of methods and technologies. Most modern spectrum analyzers use Analog-to-Digital Converters (ADCs) to convert the time-domain signals input at the port of the spectrum analyzer to frequency domain data using Fast Fourier Transforms (FFTs). Some spectrum analyzers, typically those ..

Unlike spectrum analyzers of the past, modern signal analyzers provide additional phase (time) information that can be used for much more expansive analysis than a power sweep across frequency. Though modern signal analyzers are often still called spectrum analyzers, the capability of signal analyzers includes many features beyond what a spectrum analyzer can perform. For ..
