The Yokogawa FG310 is a synthesized function generator designed for precision signal generation across test and measurement applications. It produces standard waveforms—sine, square, triangle, and pulse—plus user-defined arbitrary waveforms with linear, step, and spline interpolation. The instrument delivers phase-continuous output, triggered burst generation, gated burst output, and DC voltage capability across a single output channel.
