Signaaligeneraattori

Signaaligeneraattori, or signal generator in English, is an electronic test instrument that produces electrical signals for testing and calibration of electronic equipment. They generate controllable waveforms used to stimulate circuits and systems during development, manufacturing tests, and educational settings. Standard models produce repetitive waveforms such as sine, square, and triangle waves; more advanced devices can generate arbitrary waveforms defined by the user (arbitrary waveform generators, AWG).

Key specifications typically include: frequency range (from very low frequencies to hundreds of megahertz or gigahertz in RF models), amplitude range, DC offset, waveform quality, modulation capabilities (amplitude, frequency, and phase modulation), number of channels, and output impedance (commonly 50 ohms). Connectors and external control options (such as GPIB, USB, or Ethernet) are also important.

Common uses of signaaligeneraattore include calibrating and testing oscilloscopes, receivers, amplifiers, and filters; simulating sensor outputs; RF front-end development; and educational demonstrations. They are employed in electronics laboratories, manufacturing test benches, and field environments, often as part of broader testing and measurement setups.

Variants of the instrument span from basic function generators to RF signal generators and dedicated AWGs. Modern units frequently integrate digital synthesis for precise, repeatable control and may offer multiple channels, advanced modulation schemes, and software interfaces for complex test sequences. The technology has evolved from analog oscillators to versatile, digitally controlled devices that support a wide range of signal generation needs.
