Devices and methods for sampling an analog signal to perform data analysis are disclosed. The sampling devices and corresponding methods include a detector module that measures a response generated from a sample, an analog to digital converter that samples the analog signal, received from the detector module, and converting it into a digital signal, a sampling rate of the converter being faster than the response of the sample; and a logic circuit coupled to the converter that processes the digital signal in a frequency domain to generate a reduced digital data signal, the logic circuit processing the digital signal acquired from the converter to generate a continuous data transfer to a processing system.
