矢量网络分析仪附件常见问题

R&S®ZV-Z9x 和 R&S®ZV-Z19x 测试端口电缆系列有何区别？

即使采用优质的矢量网络分析仪，质量不佳的网络分析仪测试电缆和连接器也会阻碍分析仪顺利连接被测设备。罗德与施瓦茨希望确保矢量网络分析仪的信号完好无损地传输到被测设备，而不会损坏信号完整性或电压。正因如此，我们提供结构坚固并具有一流相位和幅度稳定性的电缆。R&S®ZV-Z9x 和 R&S®ZV-Z19x 系列都具有出色的射频质量：R&S®ZV-Z9x 电缆的核心在于抗机械性压力、连接稳定、回弹和定位阻力极低。R&S®ZV-Z19x 系列将智能线缆和高性能标准连接器相结合。

应该选择电子校准单元还是手动校准套件？

电子（自动）校准单元会自动采用集成的校准标准件：开路器、短路器、匹配负载和（未知）直通。无需手动连接校准标准件。因此，自动单元能够非常方便、快捷地进行校准，并尽量减少操作错误，例如校准时混用标准件或连接的可重复性不佳。此外，可以重复连接校准单元，以便校准超出校准单元端口数量的测试端口；例如双端口单元可以校准四端口矢量网络分析仪，甚至是具有 24 个端口的中档 R&S®ZNBT。但是，自动校准单元仅限用于连接器类型和极性特定的应用（不包括用户支持的重新特征校准应用），并且不支持单个标准件。

手动校准套件更加灵活，包括单个高端套件或两个经济型套件（分别为阳性和阴性），并支持所有阳性/阴性组合。标准件可用于单向双端口校准，也可与线缆结合以用于 TRL 和其他特殊校准。另外，标准件也可用作辅助组件，例如用于终止测试端口或进行直通连接。

R&S®ZV-Z4xx 系列等验证套件有何用途？

即使精心校正了系统误差，也需要验证校正后的精度：例如，校准套件老化、连接的可重复性有限和实际测试参数可能导致在实际条件下存在不确定度，并与理想的数据表规格存在偏差。但是，简单地重新连接之前使用的校准标准件会误导用户，而且仅能反映校准步骤的可重复性，无法揭示严重的校准错误。可靠的不确定度验证需要使用不同于校准标准件的 S 参数对已知设备执行附加测量：R&S®ZV-Z4xx 验证套件中包含的组件支持此类测量。最后，R&S®ZNA-K50(P) 选件支持验证程序，并显示带实际误差棒的测量迹线。

R&S®ZV-Z3xx 内联校准单元的工作原理和应用情况如何？

进行矢量网络分析仪系统误差校正时，需要在每次校准时连接校准设备（手动套件标准件或校准单元），然后在校准完成后断开连接。但是，一些应用中参考面并不可用，其中最重要的一个用例便是热真空腔 (TVAC) 应用：此类应用通常需要在冷却和排气后再次进行校准。适用解决方案便是内联校准单元。内联校准单元始终连接到参考面，可以通过远程控制一键启动重新校准。
