摘要
介绍了JJF1057-1998数字存储示波器校准规范中所采用的校准原则、校准思想和校准技术。针对示波器实际应用中需要面对的一系列问题,讨论并比较了模拟示波器和数字示波器各自的优缺点,介绍了数字示波器的功能与性能;对示波器及其指标分类也进行了介绍,提出了数字存储示波器的一种校准思想:满足应用需求的部分性能校准思想。同时,将硬件特性指标和软件方法指标分开处理,硬件指标纳入计量体系,而软件、方法则使用理论分析和仿真解决。叙述了在该思想下实施校准的具体技术措施:模型化测量方法;介绍了该思想下的校准技术原则:通用性原则、溯源性原则、最简捷原则、高精度原则。
All of calibration tenet and calibration ideas and calibration techniques in JJF 1057-1998 the calibration specification of digital storage oscilloscopes （DSO） are introduced. In allusion to a series of problems in application of oscilloscopes, both the merit and demerit about analog oscilloscopes and DSO are discussed and compared in detail. Both the function and the performance of DSO are introduced, both the oscilloscopes and its specifications classify are presented, and a calibration idea of DSO is put forward, that is the partial performance calibration method to fulfil the use. At the same time, dealing with the hardware specification and the software specification apart, the hardware specifications are brought into calibration, and the software specifications are treated with theory analysis, and software simulation. In this calibration thought, the main manners of calibrating the DSO are modeling measurement methods, the main technical tenets are the universal tenet, the traceability tenet, most simple tenet, and the high precision tenet.
