FFT vout of LC oscillator usin averaging spectrum analyser

Hi, I need to plot the fft of the vout of a LC oscillator using Averaging spectrum analyzer (if is posible). I connect port 1 of spectrum analyzer to vout. where i connect port 2, to obtain the transfer function? The transfer function would a delta of frequency 400Hz

Thanks, Néstor

Hi, i attached the images of my model and the result i obtain. "the averaged transfer function is a constant of value 1" i need to obtain the delta at frequency 400 Hz

Thanks, Néstor
