Function Generator

Function generators are essential electronic test equipment used to generate various waveforms, including sine, square, triangle, and pulse waves, for testing and characterizing electronic circuits and systems. These instruments work by synthesizing the desired waveform using internal oscillators and signal processing techniques. They allow precise control over frequency, amplitude, offset, and duty cycle, enabling engineers and researchers to simulate real-world signals and analyze circuit responses. Function generators support workflows in circuit design, troubleshooting, educational laboratories, and research settings, providing versatile signal sources for a wide range of applications. These applications often include testing audio equipment, calibrating sensors, simulating sensor signals, and driving actuators.

Function generators support workflows in circuit design, troubleshooting, educational laboratories, and research settings, providing versatile signal sources for a wide range of applications. These applications often include testing audio equipment, calibrating sensors, simulating sensor signals, and driving actuators. A function generator's capability to produce diverse waveforms makes it invaluable in various scientific and engineering disciplines. For instance, in spectroscopy, function generators can modulate light sources for specific measurements. In chromatography, they can control pumps and detectors for precise sample analysis. Researchers also employ function generators for sample preparation by controlling stirrers and ultrasonic baths. While brands like Tektronix, Keysight, and Rigol offer advanced function generators with features like arbitrary waveform generation and modulation, simpler models from brands like BK Precision and Siglent cater to basic educational and testing needs. Choosing the right function generator depends on the specific application requirements, such as frequency range, waveform fidelity, and modulation capabilities. ALT carries a wide selection of pre-owned, refurbished function generators. Every unit includes a standard 90-day warranty, with the option to upgrade to a three-year warranty, plus ALT's lifetime support for as long as you own the equipment. Refurbished function generators from ALT typically cost 50%-80% less than buying new, making it easier for labs to get the equipment they need without straining their budget. - Less
