主要特点
r&s®smm100a 矢量信号发生器在 100 mhz 至 44 ghz 的频率范围内提供一流的射频特性。这款仪器覆盖现有无线标准所使用的 6 ghz 以下的频段、
新定义的最高 7.125 ghz 的 5g nr fr1 和 wi-fi 6e 频段以及最高 44 ghz 的 5g nr fr2 频段。
r&s®smm100a 内置基带发生器,支持最高 1 ghz 的射频调制带宽。
因此,该仪器能够按照通用无线标准的要求生成数字调制宽带信号。r&s®smm100a 能够充分满足未来的带宽要求。
在 1 ghz 射频频率下,r&s®smm100a 矢量信号发生器的 ssb 相位噪声小于 –129 dbc,偏移值为 20 khz。典型值为 –134 dbc,进一步降低了 5 db。
该仪器不仅具备出色的射频性能,在高频条件下还展现出一流的调制特性。例如,在 28 ghz 射频频率下,r&s®smm100a 可根据 3gpp 测试模型 3.1 针对 100 mhz 的 5g nr 信号提供小于 –42 db (0.8%) 的卓越 evm 性能。
evm 性能测量值
28 ghz 载波频率下利用 3gpp 测试模型 3.1 针对 100 mhz 5g nr 信号的 evm 测量值
调制带宽内的信号频率响应同样会显著影响可实现的 evm 性能。因此,需要尽量在发生器的整个射频频率范围内降低幅度和相位频率响应。
r&s®smm100a 通过智能方式补偿对频率响应产生的内部影响。因此,在整个 1 ghz 射频调制带宽范围内,r&s®smm100a 测得的幅度频率响应小于 0.4 db。
i/q 调制频率响应测量值
r&s®smm100a 标配为支持最高 120 mhz 的射频调制带宽。用户可以根据具体要求安装许可密钥,将仪器支持的射频调制带宽扩展至 1 ghz。仪器的任意波形内存也可以从 64 msample 灵活扩展至最高 2 gsample。
r&s®smm100a 还可以使用各种频率选件,将频率最高扩展至 44 ghz。由此,用户可以精确配置 r&s®smm100a 以满足自己的实际要求。
重要软件和硬件选件概览
以图形方式实时监控信号
r&s®smm100a 非常适用于根据重要的无线通信标准生成信号,而且是适用于 5g nr 基站一致性测试的理想信号发生器。
配备 r&s®smm-b1044 频率选件后,仪器能够覆盖最高 7.125 ghz 的 5g nr fr1 频段和最高 44 ghz 的 fr2 频段。带宽扩展至 1 ghz 后,仪器能够满足 5g 应用中不断提高的信号带宽要求。
用于 5g 新空口的测试用例向导
5g nr 测试用例向导有助于方便巧妙地配置 r&s®smm100a, 以便根据 3gpp ts 38.141 执行基站收发信台测试。
wlan 同样显现出更高频率和更大带宽的发展趋势。wi-fi 6e 技术将使用 5.8 ghz 至 7.125 ghz 的频率。ieee 802.11be 等未来的 wlan 标准早已规定 320 mhz 的信号带宽。
借助高达 7.5 ghz 的 r&s®smm-b1007 频率选件和带宽扩展至 500 mhz 的 r&s®smm-k524 选件,r&s®smm100a 信号发生器非常适用于执行组件、模块和设备的 wlan 测试。
ieee 802.11ac wlan 信号的 evm 测量
r&s®smm100a 非常适用于 hrp uwb 接收机测试。该仪器覆盖高达 10.6 ghz 的频率范围,射频调制带宽为 500 mhz,能够在重要通道中生成信号。
r&s®smm-k149 hrp uwb 基带选件支持三种规定的信号生成模式:ieee 802.15.4a-2015 规定的 hrp uwb 模式以及 ieee 802.15.4z 针对增强型测距设备 (erdef) 规定的基础脉冲重复频率 (bprf) 模式和高脉冲重复频率 (hprf) 模式。
