Definition
Noun: 1. Cathode-Ray Oscilloscope: An electronic instrument that provides a visual representation (waveform) of electrical signals by displaying their voltage over time on a screen. It is used for measuring, analyzing, and troubleshooting electrical circuits.
Usage
- The primary use is to observe the precise waveform of an electrical signal.
- It is a standard tool in electronics laboratories, engineering, and telecommunications.
Examples
- Noun:
- The engineer used a CRO to diagnose the fault in the amplifier circuit.
- Observing the signal on the CRO confirmed its frequency and amplitude.
Advanced Usage
- "to trigger a CRO": To stabilize a repeating waveform on the screen by synchronizing the display with a specific point in the signal.
- You need to trigger the CRO correctly to get a clear picture of the pulse train.
Variants and Related Words
- Oscilloscope (O-scope): The more common full term and synonym for CRO.
- Digital Storage Oscilloscope (DSO): A modern type of oscilloscope that digitizes and stores waveforms.
Synonyms
- Oscilloscope
- Scope (informal)
- Waveform monitor
Related Phrases
- CRO screen/probe: Refers to the display or the input connector of the instrument.
- Connect the CRO probe to the test point.
Notes
- While "CRO" is a specific technical acronym, in general technical English, the term "oscilloscope" is more universally used. The definition provided focuses on the core function of the instrument.
Noun
- electronic equipment that provides visual images of varying electrical quantities
