A more suitable instrument for measuring electromagnetic interference is a Spectrum Analyzers. A spectrum analyzer is an instrument that displays the law of voltage amplitude as a function of frequency.

A Spectrum Analyzer is an instrument that studies the spectral structure of an electrical signal. It is used to measure signal distortion, modulation, spectral purity, frequency stability...

Now, Arbitrary Waveform Generator (AWG) and Function Generators​ (FG) can overcome these difficulties and provide unprecedented flexibility to provide engineers with a variety of signals.

The arbitrary waveform generator from the Arbitary Waveform Generator supplier not only has the signal generation capability of other signal sources

The High Quality Function Generator provides a signal source for electronic products, and can output sine wave, square wave, triangle wave, pulse and arbitrary waveform

The Pulse/Pattern Generators China can not only generate simple pulse, burst and continuous pulse streams as described above.
