Handheld spectrum analyzer/Signal analyzer
Recently, a lot of equipment have taken the high frequency or microwave technology according to the advancement and the spread of the telecommunication equipment. As a result, the handheld spectrum analyzer to analyze the signal by the frequency domain is necessaries now. The handheld spectrum analyzer is roughly classified into a heterodyne method and a Fourier transform method. The heterodyne method is also called the swept frequency method and makes it possible to measure up to tens of GHz though only for the steady signal. On the other hand, the Fourier transform method is also called the real time method and can handle an unsteady signal though the low measuring frequency range up to tens of MHz. As for our spectrum analyzer or signal analyzer, the MSA300/400 series adopts the swept frequency method, and the MSA500 series adopts both the swept frequency method and the Fourier transform method.
