Oscilloscope
makerAn oscilloscope is an electronic test instrument that graphically displays varying signal voltages as a waveform.
expanded
Oscilloscopes are critical in observing the change of an electrical signal over time, permitting engineers and technicians to diagnose performance of electronic devices. They are widely used in laboratory testing, production line quality control, and field service applications by providing features such as frequency measurement, signal analysis, and pulse width modulation.
examples
In a laboratory, an oscilloscope is used to measure the frequency response of a voltage signal from a signal generator.
This is commonly performed during the development phase of electronic circuit design to ensure system reliability.
During automotive diagnostics, oscilloscopes are used to visualize the operation of the vehicle's communication and sensor signals.
Technicians use an oscilloscope to troubleshoot real-time issues in the vehicle's electronic control system.
In power supply quality testing, oscilloscope is used to measure ripple voltage.
Manufacturers employ this method to ensure that power supplies comply with design specifications, such as maintaining a ripple voltage under 50mV peak-to-peak.
