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

I believe the function documentation is incorrect. It has however been fixed in the latest release, i.e. ADS 2004A.
Here is the relevant 4A doc.
The actual syntax should be:
y = tdr_sp_gamma(Sii, delay, Tstart, Tstop, NumPts, window)
Examples
x = tdr_sp_gamma(S(1,1), 0.05ns, -0.2 ns, 3.8 ns, 401, "Hamming")
The two commas are also wrong and fixed in 4A.
Thanks
