6. Načini rada

6.1 Oscilloscope Operation

The oscilloscope function allows for detailed waveform analysis in various applications.

Slika 6.1: Pramples of oscilloscope applications, including LIN Bus troubleshooting, audio signal analysis, and power ripple detection.

Normal Trigger Mode

In normal trigger mode, the oscilloscope waits for a trigger event before displaying a waveform. If no trigger event occurs, the screen remains blank or displays the last triggered waveform.

Način rada sa jednim okidačem

Single trigger mode is used to capture non-repetitive or transient signals. The oscilloscope waits for a trigger event, captures one waveform, and then stops. This allows for detailed analysis of a single event.
