Abstract: A description is given of the integrated instrument control and data-acquisition electronics and the software of the neutron reflectometer ROG. For the data acquisition, VME electronics is developed to perform time-of-flight and stroboscopic measurements, using a single 3He detector or a two-dimensional position-sensitive detector. For the latter pixel-dependent discrimination is implemented. The instrument control is performed via a distributed (field bus) system. A flexible integrated software system controls the complete instrument.
