The Yokogawa FG320 is a dual-channel synthesized function generator delivering precision waveform synthesis across demanding test, measurement, and design applications. It generates sine, square, triangle, pulse, and arbitrary waveforms with frequency resolution to 1 µHz and supports complex modulation, sweep, and sequencing operations. The instrument excels in mechatronics, vehicle testing, and industrial environments where signal fidelity and parameter control are critical.
