Easily Measuring: Capacitive screen touch & gesture operation, cursor measurement, when manually reading amplitude-frequency parameters, and you can directly get the peak-to-peak value and frequency without reading the background scale unit and quantityLissajous
Graphic Display & FFT Viewing: Lissajous graphic display function can be used to compare the amplitude, frequency and phase of the two sets of signals. FFT viewing function can roughly estimation of the harmonic content of the signal
