Its purpose is to show signal's spectrum
fs = 1000;
x = sin(2*pi*200*(0:1999)'/fs);
hsb = dsp.SpectrumAnalyzer('SampleRate', fs);
step(hsb,x)
If you want to see the time domain waveform, you should use dsp.TimeScope instead
fs = 1000;
x = sin(2*pi*5*(0:1999)'/fs);
hts = dsp.TimeScope('SampleRate',fs,'TimeSpan',2);
step(hts,x)
