Hi,
I am simulating a RF PA DAC at 1.88GHz. The PA output's amplitude is modulated with a signal of 1MHz with a sampling clock of 300MHz. I want to do a fft on the transient waveform to see the aliases od +- 300 MHz +- 1MHz on each side of the carrier.
My question is how to setup the strobeperiod, transient time, max time step, and all the other options in the transient simulation, and how to define the fft as a function (I am fimiliar with the dft function but I dont know how to setup the parameters).
Can someone give me a thorough explanation on how to do so?
Kind Regards,
