I have Simulink model built as top left, spectrum analyzer showing real-time fft at the bottom left, and I typed: spectrumTable = getSpectrumData(scopext) in command window trying to get data from spectrumanalyzer every 20ms(each frame), and then it shows the error on the right "too many output arguments". Anyone knows how can I achieve it?

scopext is a function to register scope extensions in various situations. With no input arguments you would probably end up running the one from the Signal Processing Toolbox, or possibly the Fixed Point toolbox. Neither of those return any output value, so you cannot use them in the form getSpectrumData(scopext)
Perhaps there was reason you expected scopext to be a variable that you had assigned a <https://www.mathworks.com/help/dsp/ref/dsp.spectrumanalyzer.getspectrumdata.html Spectrum Analyzer System Object to.
