What are DC power supplies used for?
333A DC power supply provides a constant bias voltage or current to an electrical device, component, or circuit to ensure that the device under test operates as intended. ,
View Full VersionWhat is the difference between a DC power supply and an AC power supply?
交流电适用于通过电网系统远距离输电和配电。
直流电是一种单向电荷流，比交流电更可靠，但不适合远距离输电。 大多数电子器件都使用直流电，因为它们的电压是恒定不变的，例如使用电池供电的器件。 有些器件也会使用整流器将交流电转换为直流电。 电源通常具有内置整流器和变压器，可以将电压提高或降低到合适的水平。

What are the main types of spectrum analyzers?
441There 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...
