摘要
无线电产品、通讯产品和数字产品进入美国市场,都要求进行美国联邦通信委员会(FCC,Federal Communications Commission)的认可。占用带宽(OBW,Occupied Bandwidth)是作为射频(RF,Radio Frequency)测试项目中一项重要技术指标,其衡量通信产品的整个信道发射出来的能量所占用的宽度。通过对占用带宽的测试方法深度解读,消除在20dB占用带宽和99%占用带宽测试用例上的误解。同时针对传统FCC占用带宽测试系统与中心现有的电磁兼容(EMC,Electromagnetic Compatible)系统进行对比和验证,从而提出新的测试系统搭建方法。这种方案的提出,为出口检验部门和第三方检测实验室提供了多样化的测试选择。
The putting of radio, communications and digital products on the U.S. market, usually requires the approval test by FCC. Occupied bandwidth is an important technical indicator in RF test, and this test measures the occupied width of the energy emitted from the entire channel. The in-depth interpretation of the test methods for occupied bandwidth could eliminate the misunderstanding on between 20dB and 99% occupied bandwidth tests. Based on comparison and demonstration of FCC test system and existing EMC system in testing center, a new construction of test system is proposed. And this scheme provides a variety of test solutions for export inspection departments and third-party testing laboratory.
