Concurrent RF transmission and reception would be beneficial for many applications in NMR such as imaging of short T2-samples. Since the isolation achieved by decoupling of transmit and receive paths is typically not sufficient neither robust, the sideband excitation approach is applied to isolate the excitation pulse from the retrieved data. In conjunction with a custom excitation chain and spectrometer, images have been acquired using the SWIFT sequence with continuous excitation and reception. RF transmitter infidelities are captured by a real-time monitoring of the RF chain allowing reconstructing the data on the excitation pulse as measured in the coil.
