Automatización de mediciones con analizador de espectro, detección automática de portadora y medición de THD

摘要

The objective is the automatic detection of carriers in the range from 100 kHz to 1 GHz with levels of signal greater than a configurable threshold using a spectrum analyzer Agilent Technologies N9320A to calculate the total harmonic distortion (THD) associated to the desired carrier. The automation consist in the postprocessing data considering the obstacles and drawbacks present in the measurement at high frequency, setting the variables into a GUI developed in MATLAB with a focus versatile for the user.
