Arbitrary waveform generators are a type of signal generator that generate realistic waveforms and provide a wide range of excitation signals. The various types of signals they generate are often used to stress test devices for communication protocols.
Network analyzers perform component characterization tests. A network analyzer provides a calibrated excitation signal to an RF network or device under test (DUT) and measures the vector response at frequency with phase and amplitude information. A VNA provides transmission (transmission coefficient, insertion loss, gain), reflection (reflection coefficient, VSWR, return loss), and impedance measurements, as well as s...

View Full VersionIn 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". ...
View Full VersionThis article will detail the basics of a clamp meter and the principles of measurement. When it comes to instruments that measure current, many people may think of analog or digital multimeters. However, if you want to make measurements without breaking the circuit, a clamp meter is recommended. Direct wiring method ...
