The raw signal can be plotted in real-time and selected frequencies can be filtered out. Moreover, a real-time time-frequency plot showing the fast Fourier transform (FFT) over time can be displayed. In this data visualization, the plotted data can be filtered using freely specifiable kernels, e.g. allowing Gaussian window averages or simple averages. Additionally, a choice between logarithmic and linear plot scale can be made, there is an automatic artifact removal option and more.
