We present the design and implementation of a measurement system that enables parallel drive detection small currents voltages at numerous electrical contacts to multi-terminal device. This system, which we term feedback lock-in, combines digital control-loop with software-defined lock-in measurements dynamically source measure small, pre-amplified potentials. The effective input impedance each current/voltage probe can be set via software, permitting any given contact behave as an...
