We present an instrument designed and built to the purpose of characterizing precision angular actuators with a resolution surpassing the best devices on the market. The noise of the device is better than 1 nrad/√Hz in the band from 0.1 Hz to 10 kHz on two orthogonal axes. We synthetically describe the working principle, the practical realization and the case study on a top-level commercial angular actuator
