Hello everyone, I am trying to do a intermodulation simulation for my system giving two sinusoidal frequencies at 20Mhz. But I dont know what two input frequencies to feed into my system to get the output spectrum using DFT function in spectre calculator. I tried feeding 20 and 19Mhz signals and did a DFT with hamming window but the two tones in spectrum are spread into bins on both sides.
Can anyone help me how to do this test and see the output spectrum with two singal tones and intermodulated tones.
Thanks, Yagi
