HEAO-A卫星的扫描调制准直器X射线仪器的设计目的是测量1至15千电子伏范围内的天体辐射，并将X射线源的位置与天球上的可见光源的位置分辨和关联到5角秒以内。通过对仪器观察到的X射线源进行机械准直，可以实现位置精度。高灵敏度由两个系统提供，每个系统包含四个充气比例计数器，然后是前置放大、信号求和、脉冲高度分析、脉冲形状鉴别、X射线事件计数器和遥测处理电子设备。
The Scanning Modulation Collimator X-ray instrument for the HEAO-A satellite was designed to measure celestial radiation in the range between 1 and 15 KeV and to resolve, and correlate, the position of X-ray sources with visible light sources on the celestial sphere to within 5 arc seconds. The positional accuracy is made possible by mechanical collimation of the X-ray sources viewed by the instrument. High sensitivity is provided from two systems each containing four gas fllled proporticnal counters followed by preamplification, signal summing, pulse height analysis, pulse shape discrimination, X-ray event accumulators and telemetry processing electronics.
