The Quantum Source and Measurement (QSM) module is designed for DC transport experiments, qubit characterization, and operations with DC pulses. Integrating both sourcing and measurement capabilities in a single instrument, it is supported by the DC Cluster mainframe for ground-loop free operation and interference isolation. Featuring 8 re-configurable DC input/output channels with 28-bit resolution and a <0.6 μV step size over a +/- 10 V range, it also offers a pA-uA current measurement range. This scalable system supports up to 160 channels, providing long-term stability and ultra-low noise levels. QSM modules operate seamlessly with other Qblox baseband modules for rapid experimental transitions.
