A Network Analyzer is an instrument used to analyze the properties of electrical networks, associated with the reflection and transmission of electrical signals. An analog spectrum analyzer uses either a variable bandpass filter whose mid-frequency is tuned through a range of frequencies to be measured. A digital spectrum analyzer computes the Fast Fourier transform (FFT), a mathematical process that transforms a waveform into the components of its frequency spectrum. Spectrum/Network Analyzers < 10GHz are the most popular category. The two main categories of Network Analyzers < 10GHz are: -Scalar Network Analyzer (SNA) - Measures amplitude properties only -Vector Network Analyzer (VNA) - Measures both amplitude and phase properties.
