Signal analysis using oscilloscope

The oscilloscope allows quick check of signal quality. This helps when you
do not get measurement or instable measurement. Good signal to noise
ratio and “sharpness” of signals are important to get good results

Signal-to-noise ratio (SN)

SN indicates the difference of amplitudes between the desired signal and
the noise. The higher the SN the better the signal processing

Picture 49

shows good signals with very good SN.

Picture 49 Oscilloscope menu showing good signals

There is almost no noise at all and a clear and distinguished signal.
