网络分析仪可执行元器件表征测试。 网络分析仪向射频网络或被测器件（DUT）提供经过校准的激励信号，并通过相位和幅度信息测量频率上的矢量响应。 一台 VNA 即可获得传输（传输系数、插入损耗、增益）、反射（反射系数、VSWR、回波损耗）和阻抗测量结果，以及 s 参数 S11、S12、S21、S22。
You can use the Keysight U9361 RCal Receiver Calibrator to perform an accurate and reliable calibration of your spectrum analyzer/signal analyzer by following these steps: Learn more about how to calibrate a spectrum analyzer. , and
View Full VersionUsing an arbitrary waveform generator, test engineers can verify the design of a circuit in just a few steps: (1) activate the output control; (2) select the waveform to be generated; (3) connect the output to the device under test; and (4) verify the performance of the device under test using an oscilloscope. The following is an example of the design of the output control circuit.
View Full VersionWhat is current? In this article, you will learn the difference between current and voltage, as well as the types of current and how to measure it. We all touch and use electricity on a daily basis. However, there are many things about electricity that you may not know. In this article, we will introduce you to the basics of electric current, the difference between electric current and voltage, and the types of electric current and how it is measured in an easy-to-understand...
View Full VersionSignal analyzers are capable of measuring the amplitude and phase of an input signal at a single frequency. The Signal Analyzer combines the large dynamic range of a swept-tuned spectrum analyzer with the power of a Vector Signal Analyzer (VSA) to perform in-channel measurements, such as Error Vector Magnitude (EVM) measurements, which require both magnitude and phase information. The VSAs are available in a wide range of sizes and sizes.
