In this article, we provide a brief introduction to a compact PXI-based Arbitrary Waveform
Generator/Transceiver platform used to characterize superconducting qubits. We show all-digital control and readout
of a single fixed-frequency transmon qubit coupled to its two neighbors in an 8-qubit processor. Qubit’s coherence did
not change from the values measured with a “reference” setup utilizing traditional I/Q up- and down- conversion built
from high-end stand-alone oscillators, AWG, digitizer, mixers, and other devices.
