由于传输/反射测试装置可以仅从一个端口获取并仅测量与该源端口对应的两个S参数，因此它不能执行全2端口校准，因为完整的2端口校准需要能够同时来源
端口并测量端口对的所有4个S-params。
增强响应校准是当您有传输/反射测试装置时可以执行的最佳类型的校准，并且我知道至少在E5071C ENA上支持校准类型，*但*我认为到目前为止ENA
可能只能用机械校准套件支持该校准。
在ECal的情况下，您可以使用1端口校准来校正S11测量值，但是您需要通过Thru Response校准来校正您的S21测量值。

Since a transmission/reflection test set can source from just one port and measure just the two S-parameters corresponding to that source port, it cannot do a FULL 2-port cal, since a full 2-port cal requires being able to source both ports and measure all 4 S-params for the port pair. An
Enhanced Response Calibration is the best type of cal that can be performed when you have a transmission/reflection test set, and I'm aware that type of cal is supported on at least the E5071C ENAs, *but* I think thus far ENA may only be supporting that cal with mechanical cal kits. In that case with ECal you can do a 1-port cal to correct your S11 measurements, but you would need to do a
Thru Response cal to correct your S21 measurements.
