Advanced schemes of parallel excitation build upon the close and accurate interplay between several RF channels and gradient waveforms. We present a method based on gradient magnetic field monitoring to measure the temporal evolution of both, the gradient magnetic field (in principle to higher orders) and the RF excitation pulses played by multiple transmit channels fully concurrently a system which is independent from the scanner and the coil array.
