DSP TOOL BOX NOT WORKING Spectrum Analyzer For Two-Sided Power Spectrum

I have DSP TOOL BOX with MATLAB Version 9.0 (R2016a)
The following MATLAB EXAMPLE results in an error. There is a note that states For versions earlier than R2016b, use the step function to run the System object algorithm. The arguments to step are the object you created, followed by the arguments shown in this section.
For example, y = step(obj,x) and y = obj(x) perform equivalent operations.
But I am not sure how to do this. Can someone show me how to incorporate this step function? Thanks
sin = dsp.SineWave('Frequency',100,'SampleRate',1000);
sin.SamplesPerFrame = 1000;
scope = dsp.SpectrumAnalyzer('SampleRate',sin.SampleRate);
for ii = 1:250
x = sin() + 0.05*randn(1000,1);
scope(x);
end

This worked for me:
sin = dsp.SineWave('Frequency',100,'SampleRate',1000);
sin.SamplesPerFrame = 1000;
scope = dsp.SpectrumAnalyzer('SampleRate',sin.SampleRate);
for ii = 1:250
x = step(sin) + 0.05*randn(1000,1);
step(scope,x);
end
