iFFT in Network analyzer

Question asked by hfler on Dec 7, 2012
Hi!

in NWA is an option to see the complex  Sparametr in time domain. it is done with iFFT. my Question is how is this process done?

I choose for exemple 40 frequencies betwen 4GHz and 5 GHz. these frequencies will be sent throgh a DUT. did the NWA save these S parameters of 40 frequencies and make an ifft from them?

thank you !
