How many elements do you want? Note that you should have at least enough to satisfy the Nyquist frequency. As long as you have that, you're free to have as many elements as you want define the 0.2 seconds. How about a million points?

Choose Fs, generate broadband noise, filter with a bandpass:
Fs = 44100;
Tmax = 0.2;
Samples = Tmax*Fs;
noise = randn(Samples,1);
noise = bandpass(noise,[950 1050],Fs);
pspectrum(noise,Fs)
