为了评价W-CDMA基站的性能,必须对码域功率、波形质量和其它项目进行分析,而这些测量在以前需要大型的测量仪器。这些设备的运输既麻烦又很消耗时间,因此,对于体积小、重量轻而且可以现场使用的测量仪器的需求一直以来都很强烈。UMTS Master MT8220A(见图1)是一种电池驱动的便携式基站测试仪,它体积小,重量轻(313 mm×211 mm×77 mm,重量不超过2.9 kg),它能够测量码域功率、波 In order to evaluate the performance of a W-CDMA base station, code domain power, waveform quality and other items must be analyzed, and these measurements previously required large measuring instruments. The transportation of these devices is both cumbersome and time-consuming, so the need for small, lightweight and field-usable measuring instruments has always been strong. The UMTS Master MT8220A (see Figure 1) is a battery-powered, portable base station tester that is small in size and light in weight (313 mm × 211 mm × 77 mm, weighs less than 2.9 kg) and is capable of measuring code domain power, wave
