How to use spectrum analyzer to measure EMI

Mar. 09, 2017

Spectrum analyzer is a certain frequency range in the scanning receiver, the measurement of electromagnetic interference is more suitable for the spectrum analyzer.

The spectrum analyzer is a kind of instrument which shows the variation of voltage amplitude with frequency. The spectrum analyzer overcomes the disadvantage of the oscilloscope in the measurement of electromagnetic interference, it can accurately measure the interference intensity of each frequency.

For the analysis of electromagnetic interference, the spectrum analyzer is more useful than the oscilloscope. The spectrum analyzer can directly display the signal spectrum components.

We can also supply the power analyzer, digital multimeters etc. Welcome to contact us.
