摘　　要：主要介绍了JJF1152—2006《任意波发生器校准规范》中所采用的校准原则、思想和技术。针对任意波发生器实际校准和应用中需要面对的一系列问题,讨论了任意波发生器的技术内涵和实质;提出了其校准的主导思想:仪器设备的校准、波形生成能力的校准、波形生成质量的校准;确定了校准的主要内容:仪器设备极限参数的校准和失真特性的校准;介绍了任意波发生器校准所采取的技术措施:虚拟仪器模式下的模型化测量方法;讨论了校准仪器设备选取原则:通用性原则、溯源性原则和最简捷原则和高精度原则。针对主要校准项目参数,讨论了几种典型校准方法的优缺点。The main target of this paper is to introduce all of calibration tenet, calibration ideas and calibration techniques in JJF 1152--2006, the calibration specification of Arbitrary Waveform Generators（AWG）. In allusion to a series of problems in calibration ＆application of AWG, what＇s the AWG and the connotation of AWG are discussed, the dominant calibration idea of it is put forward, including the devices calibration, the waveform producing ability calibration and the waveform quality calibration. The main calibration content are determined, including the limit parameters calibration of DUT and distortion specification calibration of DUT. Some technical steps in calibration AWG are presented, they are the modeling measurement methods. About the tenet of standard adoption, the main technical tenets include the universality, the traceability, most simplicity and the high precision. Dealing with the main calibration items, the merit and demerit of some typical calibration methods are described in detailed.
