Trapping ions, performing qubit operations and quantum multi-qubit gates require complex pulse spectra on several frequency bands. The Smart Arbitrary Waveform Generators (SAWG) Sayma and Phaser are designed to trap control and generate the Short-time Fourier transform (STFT) pulses. They have quad channels of over 1.2 GS/s (Giga Samples per second) 16-bit DACs and a few MS/s (Mega Samples per second) ADCs. These modules are dedicated to implementing qubit operations, both optically and electronically. The Sayma and Phaser modules are part of the Sinara family - a modular, open-source measurement and control hardware ecosystem dedicated to quantum applications that require deterministic high-resolution timing. The hardware is controlled and managed by the ARTIQ open-source software platform, which provides nanosecond timing resolution and sub-microsecond latency via a high-level programming language. We present the Sayma and the Phaser construction and obtained characteristics.
