How to generate a sound file with phased.FMCWWaveform

Hello,
I would like to generate a sound file (.wav) with phased.FMCWWaveform. The waveform should be between 19e3 and 20.5e3 Hz.
This is my current code:
if true
f0=19e3;
f1=20.5e3;
bw=f0:f1;
hw = phased.FMCWWaveform('SweepTime',10e-3,'SweepBandwidth',bw,'SweepDirection','Triangle','OutputFormat','Sweeps','NumSweeps',1);
plot(hw);
sf=44100;
x=step(hw);
audiowrite('test.wav',x,sf);
end
When I play the file I can hear the sound, so I assume there is something wrong. I also think, that Matlab ignores my frequency range. I would be very grateful if you could help me to solve this problem.
Best wishes, Tom
