tdr_sp_gamma()

Hi,
  I have a question about the tdr_sp_gamma() function in ADS.  When I read the help file, it shows the following...

""y=tdr_sp_gamma(S_parm_dataset, delay, reference_imped, start_time, stop_time, num_of_pts, window)

Examples
x= tdr_sp_gamma(S(1,1), 0.05ns, 50, -0.2 ns, 3.8 ns, 401,, "Hamming") ""

  However, when I try to use these parameters, the TDR does not come out right at all.  It seems that it is using the "50" as stop time, as opposed to characteristic impedance.  Are the parameters out of order in the help file?  Also, why are there 2 commas before the window parameter in the example?

Thanks,
Dan
