  Spin-orbit coupling (SOC) is an essential ingredient in topological
materials, conventional and quantum-gas based alike.~Engineered spin-orbit
coupling in ultracold atom systems --unique in their experimental control and
measurement opportunities-- provides a major opportunity to investigate and
understand topological phenomena.~Here we experimentally demonstrate and
theoretically analyze a technique for controlling SOC in a two component
Bose-Einstein condensate using amplitude-modulated Raman coupling.
