适用于 5g 大规模 mimo 基站测试

打开灯箱

主要特点

  • 相控天线阵在可调静区内(如直径为 1 m)生成平面波
  • 无需近远场变换
  • 与基于紧缩场 (catr) 的系统相比,所需空间减少四分之三
  • 内置自测试功能
  • 适用于研发和生产测试

在 5g 大规模 mimo 基站近场范围内即时测量远场特性

r&s®pwc200 平面波转换器是由 156 个宽带维瓦第天线组成的双向阵列,每个天线都位于被测设备 (dut) 的辐射近场。相控天线阵可以在 5g 大规模 mimo 基站的辐射近场中的指定静区内形成平面波,以便进行实时辐射功率和收发信机测量(误差矢量幅度、邻道泄漏比和频谱发射模板测量等)。

特性和优点

紧凑的基站测试系统设计

在近场范围内进行远场测量

r&s®pwc200 可以极大地减少远场测量所需的距离。此转换器可以在 1.5 m 的距离对孔径为 1 m、频率为 3.5 ghz 的 5g 大规模 mimo 基站进行 ota 测试。通常情况下,直接远场测量所需的测量距离为 23.5 m。r&s®pwc200 便于测试实验室和制造商节省空间,同时不会降低测量准确度。

多功能静区模拟

轻松配置静区直径和测试距离

r&s®pwc200 支持电磁场合成,且电磁场在测试装备的准确过程中进行编程。r&s®ams32-k61 场模拟软件可根据多种参数进行模拟,例如所需的静区直径和测试距离。这种灵活配置便于 r&s®pwc200 结合相同的静态测试装置测量不同大小的基站。

自动化现场校准

使用 r&s®ams32 软件在现场快速进行自动化自校准,无需任何移动

r&s®ams32-k65 场和路径损耗校准软件结合 r&s®pwc-caa1 校准天线,可在现场自动校准和验证 r&s®pwc200。此流程无需移动反向天线。这样可以简单、快速、频繁地验证并维持一流的测量准确度。

电子近场扫描

自动化功率因数校准和功率密度测量

r&s®ams32-k69 功率密度测量软件可测量 5g 大规模 mimo 基站辐射的功率密度的平面分布。此功能在无定位系统的生产测试中尤为有用。r&s®pwc200 可以针对基站的电控波束轻松验证 /- 10° 小倾斜角,并显示峰值区域。

r&s®pwc200 软件工具

全面的 r&s®pwc200 软件工具便于轻松进行配置

r&s®pwc200 可通过 r&s®ams32 系统软件或客户的特定 ota 软件进行控制。四款 r&s®ams32 工具可用作独立的可执行程序:场模拟 (r&s®ams32-k61)、场和路径损耗校准 (r&s®ams32-k65)、自测试和硬件验证 (r&s®ams32-k67) 以及功率密度测量 (r&s®ams32-k69)。用户界面布局清晰,配置数据集以 csv 文件格式显示。
