E7770A
Keysight E7770A 公共接口单元(CIU)为被测器件提供了双向中间频率(IF)接口。
Keysight E7770A 公共接口单元(CIU)可将 6 GHz 以下的上行链路或下行链路射频信号通过上、下变频转换为 6 至 12 GHz 或 7.7 至 14.5 GHz 的中频信号,从而为被测器件(DUT)提供双向中频(IF)接口。 这个解决方案为用于 5G 远程射频头(RRH)的 Keysight M1740A 毫米波(mmWave)收发信机提供了控制、电源和本地振荡器频率输入。 作为上/下变频器和 RRH 控制器,CIU 支持将频率范围从 6 GHz 以下扩展到高中频和毫米波频段。
CIU 是众多是德科技 5G 解决方案的关键组件。 这些解决方案提供了激励和分析功能,用于验证 5G 芯片、设备和基站的收发信机(Tx)和接收机(Rx)性能。
用户可以使用针对整个器件工作流程中不同测试场景设计的暗室,通过空中接口(OTA)测试来快速验证被测器件的性能。
