摘　　要：基站设备(BTS)采用时钟跟踪方式,如果时钟恶化,将导致传输质量恶化,影响GSM-R网业务。为此,提出了一种试验测试方法,测试SDH传输设备及基站控制器(BSC)时钟变化对BTS设备发射精度的影响,并提出合理化建议。Base station, or BTS, adopts a mode of clock tracking. The deterioration of clock would result in a deterioration of transmission quality and affect the services of GSM-R network.Therefore,a test method is proposed to test the impacts of clock change of SDH transmission equipment, and base station controller（ BSC） on emission precision of BTS equipment, and suggestions are given.
