串联两个直流电源需要将第一个电源的正极连接到第二个电源的负极， 形成“菊花链”连接，串联电压为两个电源的电压之和。
串联两个直流电源的步骤如下：
请注意，负载的电压应当等于或高于两个电源的电压之和，以防损坏负载或电源。 此外，负载的额定电流应当等于或低于两个电源的最低额定电流。
只能使用同一产品系列中额定输出电流相同的电源。 如果选择的电源额定电流不一致，那么最大负载电流不得超过最小额定输出电流。
此外，连接之前必须检查电源的极性，因为电源极性一旦接反，就会导致电源或连接的器件受损。
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 VersionThe article will cover the basics of impedance and points of measurement. Impedance is the resistance of an AC circuit and is invisible. Therefore, it must be measured using a specialized measuring instrument such as an impedance tester. People who have never touched an impedance tester before may be more concerned about how to use it and what to look for when using it. Therefore, this article will present in an easy-to-understand way the...
View Full VersionThere are two main types of spectrum analyzers: sweep tuning analyzers and real-time analyzers. Modern spectrum analyzers use digital signal processing to provide more measurement capabilities, making it easier for you to interpret your measurements. Whether it's a swept-tuning analyzer or a real-time spectrum analyzer, they both display the change in amplitude with frequency. However, exactly how each analyzer handles...
