Oscilloscope

1. Definition

An Oscilloscope is a test instrument that graphically displays electrical signals.
It shows how voltage varies over time, allowing you to visualize waveforms.

2. Types

  • Analog Oscilloscope: Uses cathode-ray tubes (CRT), older technology.
  • Digital Storage Oscilloscope (DSO): Captures, stores, and displays signals digitally (common today).

3. Applications

  • Observing AC/DC waveforms.
  • Measuring frequency, amplitude, duty cycle.
  • Debugging signal distortion or noise.
  • Testing PWM and communication signals.

4. Notes

Use probes correctly (compensated) to ensure accurate measurements.
Avoid exceeding voltage input limits.
