Abstract (en)
The present invention relates to a method and system for real-time monitoring noise squeezing effects of a nonlinear device and/or system (1). The method comprises the following steps:- applying a drive signal S<sub>d</sub> having a drive frequency f<sub>d</sub> to an input (3) of the nonlinear device and/or system (1) for driving the nonlinear device and/or system (1) in a nonlinear state- applying an additional probe signal S<sub>p</sub> to the input of the nonlinear device and/or system (1);- capturing an output signal S<sub>out</sub> of the nonlinear device and/or system (1);- determining, based on the captured output signal S<sub>out</sub>, a frequency spectrum of the output signal S<sub>out</sub>;- determining, based on the frequency spectrum of the output signal S<sub>out</sub>, an antiresonance frequency f<sub>ar</sub>, the antiresonance frequency f<sub>ar</sub> being a measure for the noise squeezing effects of the nonlinear device and/or system (1); wherein:the additional probe signal S<sub>p</sub> comprises a multi-tone signal having a plurality of different probe frequencies, and/orthe additional probe signal S<sub>p</sub> comprises white noise having a frequency bandwidth that is smaller than the drive frequency f<sub>d</sub>.
