Abstract
An oscilloscope includes a memory that stores instructions; and a processor that executes the instructions. When executed by the processor, the instructions cause the oscilloscope to obtain a measurement of a first radio frequency signal; split a first spectrum based on the first radio frequency signal into a first low-frequency band and a first high-frequency band; perform a first Fourier transform to compute a first new spectrum based on the first spectrum; compute a first waveform of the first new spectrum with noise of the oscilloscope reduced by performing a first inverse Fourier transform based on the first new spectrum; and combine the first new spectrum with noise of the oscilloscope reduced with the first low-frequency band.
