影响衍射最大值的位置和宽度的几何和物理像差由通过固定角度衍射的光子的能量分布确定并由固态检测器分析，在许多细节点上不同于由常规衍射仪分析的固定能量的光子的角分布确定的那些。主要的差异进行了调查，并讨论了间距测量的精度。在减少间距测量误差方面，没有简单的类似外推法的方法。
The geometrical and physical aberrations affecting the positions and breadths of diffraction maxima as determined by the energy distribution of photons diffracted through a fixed angle and analysed by a solid-state detector differ in many points of detail from those determined by the angular distribution of photons of fixed energy analysed by a conventional diffractometer. The main differences are investigated and the accuracy of spacing measurements is discussed. There is no simple analogue of the extrapolation method of reducing errors in spacing measurements.
