Definition

1. Noun:
   • Electronic instrument for visualizing electrical signals: A cathode-ray oscilloscope is a laboratory instrument that uses a cathode-ray tube to display a visual representation (waveform) of one or more rapidly varying electrical voltages as a function of time or of another voltage.

Usage Examples

• Noun:
  • The engineer used a cathode-ray oscilloscope to diagnose the fault in the circuit by observing the signal waveform.
  • In the physics lab, students learned to measure voltage and frequency using a cathode-ray oscilloscope.

Advanced Usage

• "to display on a cathode-ray oscilloscope": To show an electrical signal visually using this instrument.
  • The audio signal was displayed on a cathode-ray oscilloscope to analyze its frequency components.

Variants and Related Words

• Oscilloscope (n): A common shortened form for "cathode-ray oscilloscope."
  • The technician checked the pulse with an oscilloscope.
• CRO (n): A standard initialism for Cathode-Ray Oscilloscope.
• Digital Storage Oscilloscope (DSO) (n): A modern type of oscilloscope that uses digital sampling, often contrasted with the traditional cathode-ray oscilloscope.

Synonyms

• Scope (n, informal): A common informal synonym in engineering contexts.
• Waveform monitor (n): A device with a similar function, specifically for visualizing signal shapes.
