Is a device that is used to generate test images for display calibration. These devices are useful in calibrating a display to industry standards.
An electronic instrument used for the production of electromagnetic or acoustic signals with certain desired characteristics. It is useful in testing and calibration.
A test oscillator that can be adjusted to provide a test signal at some desired frequency, voltage, modulation, and waveform.
An electrical device that creates sine waveforms, typically of small voltages, at a variety of wavelengths as low as one Hz (cycle per second), and extending to many thousands or millions of Hz.
A test device for injecting a signal into a circuit input; the circuit's output is then read by an oscilloscope.
Same as Audio Oscillator (a device which puts out test tones at various frequencies for testing purposes).
An electronic piece of equipment used to generate waveforms. A term sometimes used when describing a carrier generator that produces CW carriers.
a device used to generate electronic test signals (or waveforms) for injecting into a circuit input; the circuit's output may then be displayed on (for example) an oscilloscope.
A signal generator, also known variously as a test signal generator, function generator, tone generator, arbitrary waveform generator, or frequency generator is an electronic device that generates repeating electronic signals (in either the analog or digital domains). They are generally used in designing, testing, troubleshooting, and repairing electronic or electroacoustic devices; though they often have artistic uses as well.
