Sweeping is done at a predetermined rate based on the sensitivity setting, which allows for more precise measurements of signals at lower frequencies. Swept-tuned spectrum analyzers are typically used to measure large spans of bandwidths at one time, such as an entire television channel. Swept-tuned spectrum analyzers sweep through an entire frequency range, in either linear or nonlinear fashion, and measure the amplitude of each frequency component along the way. Spectrum analyzers can be divided into two main types: swept-tuned spectrum analyzers and real-time spectrum analyzers. Spectrum analyzers are instruments used to measure the power of a signal across a specified range of frequencies. It’s important to note that spectrum analyzers and network analyzers are two distinct tools, even though they can both be used to measure networks.
