How do I connect two DC power supplies in series?
373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...
View Full Version网络分析仪是用于测量射频和微波器件性能的关键仪器,其类型可根据不同标准分类如下:
网络分析仪的选择需根据测量需求(如频率范围、精度、便携性)和应用场景(研发、生产、现场维护)综合考虑。矢量网络分析仪(VNA)因其全面的测量能力成为主流,而标量或手持设备则在成本敏感或移动场景中更具优势。特殊类型(如非线性或平衡式)则针对特定技术挑战设计。
是德科技提供了五种不同类型的网络分析仪系列,从高端到紧凑型全面覆盖:

View Full VersionA DC power supply converts alternating current (AC) electricity to DC electricity either by a linear method or a switching method. Switching power supplies are more efficient, lighter in weight and smaller in form factor. Linear power supplies can achieve lower noise, but this is no longer an advantage with modern switching power supplies. ,
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 ...
View Full VersionWondering about resistance measurement methods! In this article, we will cover basic resistance measurements and precautions. Resistance is very important in electronic device circuits. If the resistance is not appropriate, it can lead to malfunctions and other problems. However, electricity is not visible. To find out if the resistance in a circuit is appropriate, you need to use a specialized measuring instrument. To measure resistance, you need to use a measuring instrument...
