"if the highest peak is 1.5, does it mean at that time the field is 1.5 times high compared to the source intensity?" No, because the spectrum is calculated using fft: fft - Script command As you can see, it is not normalized to any quantity. It is only meaningful to identify the resonant frequencies, and relative magnitude at different frequencies. However, it is not possible to deduct the relation to magnitude in the source or the device. Please refer this page regarding to cw normalization: Understanding frequency domain CW normalization
