Accurate measurements of channeling radiation phenomena are important for the investigation of the validity and accuracy of theoretical calculations which are basically all approximations to the real problem. The experiment, on the other hand, also involves imperfections of various origins. The present contribution is an attempt to discuss the accuracy that can be attained in measurements of channeling radiation. Of particular importance is the determination of radiation lines and their parameters, i.e., energy, width, and yield. These, in turn, are connected to a calibration of the experimental equipment, and usually a sophisticated data analysis is required. Other experimental conditions such as beam and target quality do influence the measurements of angular distributions and coherence lengths, of which the latter is at present of particular interest for theoretical work.
