TRL校准件参数自定义，校准步骤及端口匹配设置

[{"insert":"TRL（直通、反射、线）是指测量两个传输标样和一个反射标样、以确定 2 端口 12 项误差系数的一系列校准技术。例如，TRM（直通、反射、匹配）、LRL（线、反射、线）、LRM（线、反射、匹配）均包含在这一系列校准技术中。\n传统的 SOLT 校准将测量一个传输标样 (T) 和三个反射标样 (SOL)，以确定相同的误差系数。\nTRL 校准非常精确，在大多数情况下比 SOLT 校准更精确。然而，很少有校准套件包含 TRL 标样。如果对精度要求很高，且在 DUT 相同的连接器类型中不具备校准标样，则往往执行 TRL 校准。如果使用测试夹具，或者使用探头进行晶片测量时，通常也是如此。因此，在某些情况下，您必须在与 DUT 配置相同的介质类型中构建并表征标样。制造并表征三个 TRL 标样比四个 SOLT 标样要简单得多。\nTRL 校准的另一优势在于：TRL 标样的定义不必与 SOLT 标样的定义一样完整和精确。当 SOLT 标样完全表征并存储为标样定义时，TRL 标样将会建模，但不会完全表征。但是，TRL 校准精度与 TRL 标样的质量和可重复性直接成正比。物理的不连续性（例如，传输线上的弯曲以及同轴结构中的铷珠）将降低 TRL 校准。连接器必须保持干净并允许重复连接。\nTRL校准件实物示例：\n"},{"insert":{"image":"https://www.eteforum.com/image/show/attachments-2022-08-UdEg2Byz62ff3bc51f861.png"}},{"insert":"\nl TRL校准件自定义\nKeysight E5071C
