The difference between spectrum analyzer and network analyzer
An integrated microwave measuring instrument that performs scanning measurements in a wide frequency band to determine network parameters. Microwave network analyzer. The network analyzer is a new type of instrument for measuring network parameters, complex scattering parameters can be directly measured active or passive, reversible or irreversible dual port and single port network, the amplitude and phase frequency characteristics and frequency of the scattering parameters and the. Automatic network analyzer can correct the error of measurement results by point, and figures out dozens of other network parameters, such as the input reflection coefficient, reflection coefficient, output voltage in Bobbi, impedance (or admittance), attenuation (or gain), phase shift and group delay of transmission parameters and isolation and orientation etc..
The spectrum analyzer is the instrument to study the signal spectrum structure, for the measurement of signal distortion, modulation, spectral purity and frequency stability and the intermodulation distortion signal parameters, can be used to measure some parameters such as amplifier and filter circuit system, electronic measuring instrument is a versatile. It can also be called frequency domain oscilloscope, tracking oscilloscope, analysis oscilloscope, harmonic analyzer, frequency analyzer or Fu Liye analyzer. Modern spectrum analyzer can display analysis results in analog or digital mode. It can analyze all radio frequency signals from VLF to sub millimeter band below 1 hz. If the digital circuit and microprocessor are used in the instrument, it has the function of storage and calculation, and it is easy to form an automatic test system with the standard interface.
