What is a Digital Oscilloscope and How Does It Work?
A digital oscilloscope (DSO) visualizes voltage signals over time, revealing amplitude, frequency, and noise that multimeters miss. Ideal for beginners and hobbyists, models like the Hanmatek DOS1102 (2CH) and DOS1104 (4CH) offer 110MHz bandwidth, 1GSa/s sampling, and intuitive features for electronics, Arduino, audio, and power supply testing.
