how to do the power spectral density in cadence

Hi ,,,

when using Cadence sim. analog env. , the output signal of my ckt (Transit sim.) is voltage pulse , so how we find out its power spectral density? which function we use in cadence calculator ? how?
thankx
 

cadence power spectral density

Can u explain more , please?
 

psd function cadence

you can refer to openbook for more
 

wavescan fft

Hi ,,,

For exmple we have the next shown signal , Can u show me how we determain the power spectral density of the output signals?
thankx
 

how can a psd function be used in cadence calculator.

I have designed a sigma delta modulator and i would like to see psd of its output.

Thanks in advance.
