Harmonics refer to a series of waveforms with integer multiples of frequency generated on the basis of a sine wave. Harmonic analysis is an important testing technique in power systems to evaluate power quality and fault diagnosis. Agilent oscilloscopes play a key role in harmonic analysis as advanced measurement equipment. This article will cover the applications of Agilent oscilloscopes for measuring harmonics.
1. The basic principle of Agilent oscilloscopes.
An Agilent oscilloscope is an instrument used to display signal waveforms such as voltage and current. The basic principle is to input a signal into the vertical channel of the oscilloscope, which is amplified and processed and displayed on the oscilloscope's screen. Agilent oscilloscopes use advanced digital signal processing to measure and analyze signals with high accuracy.
2. The method of measuring harmonics from Agilent oscilloscopes.
