What are spectrum analyzers used for?
497Spectrum analyzers measure the amplitude of an input signal versus frequency over the entire frequency range to determine the power of the signal. Spectrum analyzers are capable of performing tests such as noise figure and signal-to-noise ratio (SNR) to characterize the performance of a device and its contribution to overall system performance. For more information, see the application guide Spectrum Analysis Basics. ,

How to use the impedance tester
418In this article, we will describe the basic measurements of an impedance analyzer. Overview An impedance tester is an instrument used to measure AC resistance or impedance. This article will introduce the basic knowledge about impedance, the measurement method of impedance, and how to use the impedance tester. What is impedance? What is impedance? In short, it is "a quantity that indicates the difficulty of the flow of alternating current". ...
