【经验】解析Keysight四通道射频功率计设计方案
其中2通道功率计推荐使用KEysight的N1914A,可替代老款E4416A和E4417A系列产品,采用全新的LCD彩色显示屏,相比老款的液晶点阵屏,显示效果有大幅度提高。N1914A双通道功率计可兼容所有的N8480、8480、U2000系列和E系列传感器(E9320系列除外),并可在9kHz至110GHz的频率范围内进行-70至+44dBm的平均功率测量。
优势如下:
频率范围:9kHz至110GHz(取决于传感器)
宽广的动态范围:-70至+44dBm(取决于传感器)
不仅可提供 GPIB 连通性,还可提供 LAN LXI-C和USB连通性
与 E4418/19B功率计*和 436A/37B/38A功率计实现代码兼容(借助选件 200)
更多测量通道:多达三个通道,使用可选的USB主机端口可连接另外两个U2000系列功率传感器
利用可选的外部触发输入/触发输出功能自动进行频率/功率扫描测量
现在,仪器在发货时随附 BenchVue 软件许可证(BV0007B)。BenchVue能帮助您轻松连接和控制仪器,自动执行测试序列
N1914A EPM系列功率计智能支持2个传感器直接连接,这些传感器包括N8480、U2000系列和E系列传感器(E9320 系列除外)。
那么该如何能够单机支持4路射频功率测量呢?观察了新款N1914A的接口,相比老款E4417A,N1914A除了2个传统功率传感器接口,前后面板还各自增加了一个USB接口。而且KEYSIGHT是有USB接口的独立型功率传感器的,笔者咨询了厂家和翻阅用户指南,新款N1914A的2个USB接口支持Keysight自己的USB功率传感器。
与传统双通道功率计相比,N1914A支持通过可选的USB主机端口与U2000系列USB功率传感器连接,进行四通道功率测量。这样就扩展了测量通道数量,使用一台N1914A新款射频功率,直连2个功率传感器,再外接2个USB功率计,就可以进行4通道射频功率测量。通过查阅USB功率计的功率和频率范围,频率方面USB最高为24GHz,满足通信测试的常规频段。这里需要注意的是,USB功率计原本是用于户外便携测试,无需功率计主机,直接连接笔记本电脑就可以进行功率测量,精度比功率计N913A主机+直连传感器要略低1~2%。
综上所述,就可以使用一台2通道功率计+外接USB传感器即可满足4通道射频功率计需求,成功避免成本的不必要增加。
