摘要 目的 :解决微波治疗设备电磁兼容测试中辐射发射测试系统存在的非线性问题。方法 :通过对辐射发射系统各组件的分析,找出工作在非线性区域的组件,结合GB 4824—2013《工业、科学和医疗(ISM)射频设备骚扰特性限值和测量方法》中2组设备限值要求对试验系统进行改进。结果:改进后的测试系统能够准确地检测被测设备真实骚扰信号,提高了试验准确性、可靠性。结论:改进后的测试系统解决了动态范围过窄的问题,可为搭建微波治疗设备的辐射发射测试系统提供参考。 Objective To solve the problem of nonlinearity of radiation emission test system in electromagnetic compatibility test of microwave treatment equipment. Methods The components of the radiation emission testing system were analyzed to find out the components in the nonlinear area, and the testing system was improved according to the requirements for the limits of two sets of equipment in GB 4824—2013 Industrial, scientific and medical(ISM) radio-frequency equipment-disturbance characteristics-limits and methods of measurement. Results The improved testing system detected the disturbance signals for the tested equipment with enhanced accuracy and reliability. Conclusion The improved testing system solves the problems of narrow dynamic range, and provides references for the radiation emission test system of microwave treatment equipment.
