Spectrum Analyzer Measure Noise Figure Based on Y-factor Method
The noise factor is an important indicator to reflect the internal noise of the RF module.The design and selection of the RF module are inseparable from the measurement of the noise factor,so the noise factor analyzer is generally used for testing.Since not every laboratory is equipped with relevant instruments,spectrum analyzers are more commonly equipped than noise factor analyzers.In this paper,the principle of Y coefficient method is used to measure the noise factor.Through software design,the spectrum analyzer can replace the noise factor analyzer to measure the noise factor.
