今年4月,我省开始抽检数字蜂窝移动通信网基站,在测试GSM基站带内杂散辐射时,发现在935-960MHz频段内测得的数据都没达标。因此,检测人员暂停了测试工作,反复检查了测试方法和测试参数的设置,并用多种频谱仪在不同的基站上进行了试验。结果发现,在同样测试条件下,按照《900/1800MHzTDMA数字蜂窝移动通信网基站子系统设备技术要求及无线指标测试方法》(YD/T883-1999标准)中规定,将设备分辨率带
In April this year, the province began sampling the digital cellular mobile communication network base station. When testing the stray radiation in the GSM base station, it found that the data measured in the 935-960 MHz band did not reach the standard. Therefore, the tester suspended the test work, repeatedly checked the setting of the test method and the test parameters, and conducted tests on different base stations using various spectrum analyzers. The results showed that under the same test conditions, in accordance with “900 / 1800MHzTDMA digital cellular mobile communication network base station subsystem equipment technical requirements and wireless index test method” (YD / T883-1999 standard) provides that the device resolution band
