  Spin waves are studied intensively for their intriguing properties and
potential use in future technology platforms for the transfer and processing of
information and microwave signals. The development of devices and materials for
spin-wave systems requires a lot of measurement time and effort, and thus
increasing the measurement throughput by extending the instrumentation
capabilities is of the essence. In this letter, we report on a new and
straightforward approach to increase the measurement throughput by fully
exploiting the wideband detection nature of the Brillouin light scattering
technique in single-shot experiments using a white-noise RF generator.
