Product Information
- Name : Oscilloscope
- SKU : BLT-58
- Category : oscilloscopes
An oscilloscope is a core precision observation instrument in the electronics field, capable of intuitively displaying the waveform of electrical signals over time on a screen. It captures signal details such as voltage, frequency, period, amplitude, and distortion, and can observe waveforms of pulses, sine waves, and transient circuit faults. It is categorized into benchtop digital oscilloscopes, handheld portable oscilloscopes, and virtual oscilloscopes. When paired with probes, it can interface with circuit boards and electronic circuits for signal acquisition, making it an essential testing tool for circuit development, equipment maintenance, and industrial control debugging.

Working Principle
The electrical signal under test is sent into the instrument through the probe. After signal amplification and analog-to-digital sampling, the device scans and arranges the signal points based on the time base, drawing a continuous waveform curve of voltage variation over time on the display screen. By adjusting the time base, voltage range, and trigger mode, a stable waveform is locked, allowing direct reading of various electrical parameters such as signal frequency, peak value, and duty cycle.
Application Areas
1. Electronic R&D: Design and debugging of signal waveforms for circuit boards, microcontrollers, and power modules.
2. Home Appliance Repair: Waveform inspection and troubleshooting of fault points in televisions, frequency converters, and motherboards.
3. Industrial Automation: Detection of pulse signals from servo drives, sensors, and PLCs.
4. Teaching and Experiments: Hands-on teaching and practice of signal principles in university electrical and electronic engineering courses.
