Analysis the signal detail
5.3 Analyze the signal detail
If adding the random noise to the measured signal, you can adjust the settings to eliminate
or reduce the noise and then avoid the interference to original signal.
1. Observe noisy signal
The circuit fault may happen by the interference of noise signal and for a better analysis of
the noise, please follow these steps.
1) Connect Ch1 to signal.
2) Press to open the oscilloscope menu.
3) Press to select the sampling cfg as peak.
At this time, the screen displays random noise waveform and noise peak and burr can be
observed with peak sampling. See picture5-4.
