Arbitrary waveform generators (AWGs) offer solutions to measurement challenges that require drive signals of higher complexity than that of standard periodic signals. The full freedom to define the shape of a signal sample by sample allows users to tailor spectral or temporal properties and engineer the response of a device under test. This is required in quantum technology, notably, where signal shapes are optimized to achieve maximum fidelity when manipulating quantum states, or in electrical engineering to test a device exposed to a real-world signal including noise and imperfections.
The speciality of a signal generator such as the Zurich Instruments SHFSG is the synthesis of high-purity signals with precise frequency and phase control. The SHFSG Signal Generator includes the key functionalities of an AWG to generate pulse shapes directly up to 8.5 GHz based on its double superheterodyne frequency conversion scheme. The SHFQC Qubit Controller includes both signal generator and readout capabilities to realize a tailored measurement solution for superconducting qubits. The HDAWG Arbitrary Waveform Generator, with its large waveform memory, can reproduce a large number of realistic experimental conditions in a single run. The UHF-AWG is an upgrade option for the UHFLI Lock-in Amplifier that combines pulsed signal generation and measurement in one instrument.
