evaluating the output spectrum

whlinfei

Hi,

 I have finished transient simulation on my transmitter, after three days.

I can now load  the output waveform in the plot. I hope that I can extract the data and use matlab to get the power spectral density plot.

But everytime I try to load the data into a table, which is supposed to be quite large, the loading takes forever and never gave me the final  table.

Is there any  way to circumvent this problem and analyze the final spectrum ?

 

Thanks.

    I use the following method for PSD analysis in matlab. I plot the signal in wavescan (ade graphics tool) and use the menu Trace/Save to matlab format (options pop up). Then you can post process this file in matlab (remember to avoid the first row in the file). If sampling time is not constant, I sample the waveform using calculator to plot another waveform which I then post process.
