如何对校准集应用功率校准？

您需要执行“引导功率校准”，而不是分别执行ECal和源功率校准。
此校准方法将源功率校准与您选择的S参数校准（即ECal或Mechanical）相结合，并创建一个具有S参数误差项和所需源功率偏移的校准集，并为每个校准提供额外的响应功率校正优势
您的校准中的接收器。
以下是在引导校准会话期间启用功率校准的相关命令。
*引导功率校准* *使用标准源功率命令进行高级设置。* *使用功率传感器命令配置功率传感器。* *执行功率校准* * SENS：CORR：COLL：GUID：PSENsor * *功率传感器连接器类型
* * SENS：CORR：COLL：GUID：PSEN：CONN * * Cal cal for power cal * * SENS：CORR：COLL：GUID：PSEN：CKIT * * cal的功率等级* * SENS：CORR：COLL：GUID：PSEN
：POWer：LEVel * *执行匹配校正* * SENS：CORR：METHods：MATCh *有关更多信息，您可以参考_PNA在线帮助_并在索引中查找“引导功率校准”主题。

  Instead of performing the ECal and source power cal separatly, you'll need to perform a "Guided Power Calibration".  this calibration method combines the source power calibration with your choice of S-Parameter calibration (i.e ECal or Mechanical) and creates a calset that has both S-Parameter error terms and the required source power offset with the added benefit of response power corrections for each of the receivers in your cal.

Here are the relevant commands for enabling the power calibration during your guided calibration session.

*Guided Power Cal*
*Use standard Source Power commands to make advanced settings.*
*Use Power Sensor commands to configure the power sensor.*
*Perform power cal*
*SENS:CORR:COLL:GUID:PSENsor*

*Power sensor connector type*
*SENS:CORR:COLL:GUID:PSEN:CONN*

*Cal Kit for power cal*
*SENS:CORR:COLL:GUID:PSEN:CKIT*

*Power Level for cal*
*SENS:CORR:COLL:GUID:PSEN:POWer:LEVel*

*Perform match-correction*
*SENS:CORR:METHods:MATCh*

for more information you can refer to the _PNA Online Help_ and in the index look for the "guided power cal" topic.

我将在Guided Power Cal主题中添加一个注释，指示power cal部分也存储在Cal Set中。
此外，我们可以将SCPI示例用于Guided Power Cal。



     以下为原文

  I will add a note to the Guided Power Cal topic that indicates that the power cal portion is also stored in the Cal Set. Also, we could use a SCPI example for Guided Power Cal.

另请注意，引导功率校准还具有其他几个属性：1）它允许在任何端口上执行源校准，然后将其传输到VNA的任何和所有其他端口，而无需重新调整功率计测量值。
（它使用S参数cal来计算传递函数）。
2）它在与功率传感器相同的端口上执行接收器校准，然后将该校准传输到所有其他端口。
所以现在，您同时具有源和接收器校准（加上接收器的所有比率）和所有S参数3）它提供匹配校正功率，因此将消除端口和DUT之间的不匹配误差。
注意：可以在Cal：Manage Cal：Corrections Methods对话框下关闭此不匹配校正，以便它仅返回接收器的响应校正（仍然对S参数进行完全校准）。
4）所有接收器和比率也同相校准，因此您可以使用任何端口的输入来测量信号之间的相对相位。
5）所有校正，包括源和接收器校准，都可以应用固定，去嵌入，端口-Z转换和端口匹配。



     以下为原文

  Also note that the guided power cal has several other attributes:
1) it allows doing a source cal on any port, and then transferring it to any and all other ports of the VNA, without redoing the power meter measurement. (it uses the S-parameter cal to compute the transfer functions).
2) It performs a receiver cal on the same port as the power sensor, and then transfers that cal to all the other ports.  So now, you have both  Source and Recevier calibrations (plus all ratios of receivers) and all S-parameters
3) it provides for match corrected power, so that mismatch error between the port and the DUT will be removed.  Note: this mismatch correction can be turned off under the Cal:Manage Cal:Corrections Methods dialog, so that it returns only response correction for receivers (full cal is still done on the S-parameters).
4) All the receivers and ratios are also calibrated in phase, so you can use the input from any ports to measure relative phase between signals.
5) all the corrections, including source and receiver cal, can have fixturing, de-embedding, port-Z converion and port matching applied.

谢谢大家的回复。
我能够成功地使用Guided Power Cal代码，然后使用Guided ECal代码来执行全面校准。
我现在想知道，如果可以将Guided Power Cal与非制导ECal操作结合起来吗？



     以下为原文

  Thank you all for your responses. I was able to succesfully use the Guided Power Cal code, followed by Guided ECal code, to perform a comprehensive calibration.

I am wondering now though, if is it possible to combine the Guided Power Cal with an Unguided ECal operation?
