Sayma is an advanced hardware solution designed for scien tific experiments in the field of quantum physics, particularly those involving ion traps. It is a part of Sinara, an open-sour ce ecosystem developed by a collaboration between M-Labs, Warsaw University of Technology (WUT), US Army Research Laboratory (ARL), the University of Oxford, the University of Maryland, and NIST. Sayma provides a high-quality, modular, and flexible platform for generating arbitrary waveforms in ion trap experiments. This article provides an overview of Sayma, its features, and its components: the Sayma AMC (Advanced Mezzanine Card) and Sayma RTM (Rear Transition Module).

The arbitrary waveform generator is characterised by its flexible signal generation, high frequency resolution and rapid frequency switching speed and is wildly used in fields like communication, radar systems, quantum control, astronautics and biomedicine. With continuous development of technology, higher requirements are placed on to the arbitrary waveform generator. Sampling rate determines the bandwidth of the output signal, spurious-free dynamic range determines the quality of generated signal. Due to above, these two indicators’ improvement is vital. However, the existing waveform generation methods cannot generate signals with quality good enough due to their technical limitations, and in order to realize a high system sampling rate, to accomplish waveform generation process in FPGA, multipath parallel structure is needed. Therefore, we proposed a parallel waveform synthesis structure based on digital resampling, which fixed the problems existing in the current methods effectively and achieved a high sampling rate as well as high quality arbitrary waveform synthesis. We also built up an experimental test bench to validate the proposed structure.
