generators x
alphanumeric generator
In computer graphics, a character generator that produces alphabetical and numerical characters with some punctuation and symbols.
analog stroke
An analog method of moving a cathode-ray tube beam across a display screen face, commonly used in high-performance vector and character generators.
character generator
Computer hardware or firmware that accesses character patterns stored in read-only memory and displays them at specific coordinates on a screen.
diamond cutting tool
A tool made by imbedding small particles of diamond in the working edge. In the optical field, the most commonly used diamond tools are glass saws, cup-shaped tools for curve generators, and diamond...
digital delay generator
An instrument that can preselect intervals, often in increments of 1, 10 or 100 ns, for the generation of electronic pulses by means of front-panel switches. Also called a time-delay generator.
DWG
digital waveform generator
function generator
A computer hardware unit that generates required functional information on the screen by controlling CRT beam movements or intensity.
genlock
A device used to lock the internal synchronization generator of a television camera to an external source.
inductance
Inductance is a fundamental property of an electrical circuit or component that describes its ability to store energy in a magnetic field when an electric current flows through it. It is typically...
infrared signal generator
A device that combines electronic and optical techniques to form a monitored infrared signal between 1 and 14 µm. It contains an internal modulator to amplitude-modulate the output signal, an...
LGP
light-gun pulse generator
lock-in amplifier
A lock-in amplifier is a specialized electronic instrument used to extract and measure small signals embedded in noise or interference. It is particularly useful in fields such as spectroscopy,...
Marx generator
High-voltage, fast-discharge circuit named after its inventor, Erwin Marx. Its capacitors are charged in parallel and discharged in series. The voltage multiplication achieved with a Marx circuit is...
multimodal vision-language models
Multimodal vision-language models (MVLMs) are advanced AI systems designed to understand and process information that combines both visual and textual data. These models are capable of interpreting...
point-focusing collector
A device used in solar systems to direct mirror-reflected sunlight to a heat absorber and heat-driven engine, which turns a generator to produce electricity.
rare-earth elements
Rare-earth elements (REEs) are a group of seventeen chemical elements found in the Earth's crust, characterized by their unique properties and scarcity relative to other elements. Despite their name,...
regenerative repeater
A repeater that is designed for digital transmission. Also called a regenerator.
RTG
radioactive thermoelectric generator
TASR
tunable, all-optical signal regenerator
time delay generator
->
digital delay generator
An instrument that can preselect intervals, often in increments of 1, 10 or 100 ns, for the generation of electronic pulses by means of front-panel switches. Also called a time-delay generator.
