fs & Spectral power in Ptolemy

Hi:

 

I'm running some Ptolemy data into a time sink, and I'd like to get the right spectral power using the fs() command, but I'm running into trouble. When I plot dBm(fs(SignalOut)), I get a peak spectrum value that is 10 to 20 dB lower than the calculated value based on the input signal to the TimedSink. Are there any examples that go into the detail's of the output scaling in  fs()

 

Thanks
