Oscilloscopes are laboratory instruments used to measure voltage against time and draw an instant graph of the voltage. They're used for a multitude of applications, most commonly to test new electrical equipment. Oscilloscopes, along with oscilloscope accessories, are crucial in ensuring accurate measurements and diagnostics. Regular calibration is required to maintain their precision.
Oscilloscopes can display both alternating current (AC) and pulsating direct current (DC) waveforms, ranging from as low as 1Hz to several MHz. High-quality oscilloscopes can also display signal frequencies up to several hundred GHz.
The display of an oscilloscope is segmented into horizontal divisions and vertical divisions. The time is displayed along the horizontal section, and it displays the voltage on the vertical section.
For more advanced testing, integrating an oscilloscope and spectrum analyzer allows users to not only visualize waveforms but also analyze the frequency spectrum, providing a comprehensive view of the signal's behavior.
There are many types of oscilloscopes, some of which are detailed below:
Also known as a cathode-ray oscilloscope, this is the oldest type. It produces an image on the display by causing a focused electron beam to travel in patterns across the face of a cathode ray tube.
These devices are built from various software and electronic hardware modules which work together to detect, process, and display electronic signals. Digital oscilloscopes come in various configurations, such as dual channel oscilloscopes and four channel handheld oscilloscopes, offering flexibility for different measurement needs.
This type operates two or four analogue channels along with a larger number of digital channels. The benefit of this oscilloscope is there's no need to use a separate logic analyzer.
Compact and lightweight, portable oscilloscopes, also known as handheld oscilloscopes, are designed for field use or situations where mobility is essential. They often feature battery power options and rugged construction. Popular choices include portable digital oscilloscopes and 4 channel handheld oscilloscopes. The handheld oscilloscope price can vary depending on features and capabilities.
Larger and more powerful than portable models, benchtop oscilloscopes offer advanced features and higher performance. They are ideal for laboratory settings or applications requiring in-depth signal analysis.
These oscilloscopes, sometimes called USB oscilloscopes or USB signal oscilloscopes, connect to a computer via USB or other interfaces, leveraging the processing power and display capabilities of the PC. They are often more affordable and offer flexibility in data analysis and storage.
Eliminating the need for physical cables, wireless oscilloscopes provide greater freedom of movement and simplify setup in challenging environments. They transmit data wirelessly to a connected device for analysis.
Specifically designed for automotive diagnostics and troubleshooting, these oscilloscopes offer features tailored to analyzing signals from various vehicle systems, such as engine control, sensors, and communication networks.
