An AC power supply is responsible for providing AC power to the load. The power input can be either AC or DC. You need an AC power supply because the power from the wall outlet does not meet the specifications of the load. In order for the load to operate properly, you need to transform the AC power supply to tune the AC power from the supply to the voltage, current, and frequency required by the device. This can be accomplished by raising or lowering the voltage and then filtering the signal.
You can use an AC power supply for testing. The AC power supply can emulate grid outages, harmonics, surges, or other events that may cause the device under test (DUT) to fail.
Real-time spectrum analyzers can collect data in the time domain and then convert it to the frequency domain using the Fast Fourier Transform (FFT). Real-time spectrum analyzers can quickly capture transient and fast signals. ,

Measurable Devices, Measurement Methods, and Precautions In everyday life, many people say they don't know much about the frequencies of electrical appliances. However, some electrical appliances have specific compatible frequencies, and using electricity at a frequency that is not compatible with the product may lead to malfunctions, fires, and other risks. In addition, in industrial equipment, there are electrical designed to operate at fixed or variable frequencies...
View Full VersionA benchtop DC power supply is a power supply that is mounted to an engineer's workbench for use. It usually has a large, legible display and user interface to allow the engineer to easily achieve full control of the power supply from the front panel. Users can also control modern benchtop power supplies through software. In addition, engineers can easily access the output terminals from the front. Variable bench power supplies are a convenient electric...
