Saluki SE1022 DSP Lock-in Amplifier develops and integrates the function of FFT high accuracy spectrum analysis, which can realize the frequency domain analysis from 1 kHz to 102 kHz and display the spectrum distribution of the signal in real time.
FFT is Fast Fourier transformation. It is an algorithm that exacts the frequency domain information of the signal. Generally, it is hard to analyze the signal’s features in time domain. But it is easy to analyze the component of the signal at each frequency if the signal is in frequency domain. This is beneficial to evaluate the signals in all aspects. SE1022 lock-in amplifier integrates a high precision FFT analysis function in order to analyze the noise component of the measured signal in real time.
The setting of FFT is in the menu of [DISPLAY].
