Compact embedded device for lock-in measurements and experiment active control

Mostrar todas las versiones(2)

We present a multi-purpose toolkit for digital processing, acquisition, and feedback control designed for physics labs. The kit provides in a compact device the functionalities of several instruments: Function generator, oscilloscope, lock-in amplifier, proportional-integral-derivative filters, ramp...
