CalSet接口中的ComputeErrorTerms给出错误

你好Brian，你是对的，这个calset命令没有一个确切的scpi equivalen。
实际上有点奇怪。
校准通常在通道对象上完成。
在SCPI中，通常是SENSe节点。
* CLS SYST：PRESET; * OPC？
CALC：PAR：DEL：ALL CALC：PAR：DEF“myS21”，S21 DISP：WIND：TRACE：FEED“myS21”CALC：par：mnum：sel 1 SENS：CORR：COLL：METHod TRAN2 SENS：CORR：COLL：ACQ
STAN4; * OPC？
SENS：CORR：COLL：ACQ STAN5; * opc？
SENS：CORR：COLL：SAVE问候，苏

  Hello Brian,

You are correct, there is not an exact scpi equivalen for this calset command.
It is a little peculiar actually.  Calibrations are usually done on a channel object.
In SCPI that is generally the SENSe node.


 
*CLS
SYST:PRESET;*OPC?
CALC:PAR:DEL:ALL
CALC:PAR:DEF "myS21",S21
DISP:WIND:TRACE:FEED "myS21"
CALC:par:mnum:sel 1
SENS:CORR:COLL:METHod TRAN2
SENS:CORR:COLL:ACQ STAN4;*opc?
SENS:CORR:COLL:ACQ STAN5;*opc?
SENS:CORR:COLL:SAVE

Sue

苏，谢谢。
我有理由在SCPI中为DCOM / COM做我能做的事情。
我在DCOM / COM中有一个工作系统。
我们正在扩展其他一些非Keysight切换硬件，因此最好拥有所有SCPI。
感谢Tom S.和一年多前的工厂支持，我能够在DCOM / COM中实现这一目标。
我通过原始测量获得我的标准，因为我必须改变校准的顺序，然后分析仪计算误差项。
换句话说，Put_Standard_Method然后ComputeErrorTerms工作（当然也使用其他命令）。
我只需要SCPI中的相同内容。
http://na.support.keysight.com/pna/help/WebHelp9_9/Programming/COM_Reference/Methods/Put_Standard_Method.htm Put_Standard_Method“将变量数据写入_error校正缓冲区_保存针对特定标准获取的测量数据”并允许错误条款
要计算。
您的代码示例让分析器控件获得标准的度量：SENS：CORR：COLL：ACQ STAN4; * opc？
SENS：CORR：COLL：ACQ STAN5; * opc？
我需要一个“Put_Standard_Method”SCPI替代方案，然后允许“ComputeErrorTerms”SCPI替代方案，它将使用我在“纠错缓冲区”中输入的标准数据来计算错误条款。
感谢您在执行此操作时可能遇到的任何其他想法。
也许解决方案是我只需要混合DCOM和SCPI命令来获得我想要的东西。

  Sue,

Thank you.  I have reasons for doing what I can do in DCOM/COM in SCPI for this.  I have a working system in DCOM/COM.  We are expanding with some other non-Keysight switching hardware so would be best to have everything SCPI.  Thanks to Tom S. and the factory support over a year ago I was able to get this working in DCOM/COM for what we currently have.  I acquire my standards via raw measurement as I must shuffle the order of a calibration and then the analyzer computes the error terms.

In other words, Put_Standard_Method and then ComputeErrorTerms works (other commands are used too of course).  I just need the same in SCPI.   

http://na.support.keysight.com/pna/help/WebHelp9_9/Programming/COM_Reference/Methods/Put_Standard_Method.htm

Put_Standard_Method "Writes variant data to the _error correction buffer_ holding measurement data acquired for a specific standard" and allows Error Terms to be computed.

Your code example has the analyzer control obtaining the measurement for the standards:
SENS:CORR:COLL:ACQ STAN4;*opc?
SENS:CORR:COLL:ACQ STAN5;*opc?

I need a "Put_Standard_Method" SCPI alternative that then allows a "ComputeErrorTerms" SCPI alternative that will compute the Error Terms using the standard data I put in the "error correction buffer".


Thanks for any other ideas you may have on doing this.

Maybe the solution is I simply must mix DCOM and SCPI commands to get what I want.

Brian

通常情况下，最好使用校准引擎来获得校准标准，因为有时我们会做“秘密事情”以使所有校准完美，如果您使用正常的VNA扫描来获取校准数据，您可能不知道这些事情。
如果您尝试通过多端口测试集进行校准并且不想重复o / s / l标准，则有更好的方法：以编程方式加载来自calset的术语并使用未知的thru。
如果您尝试一次校准大量通道，则有更好的方法：使用cal-all功能。
大多数时候，让分析仪完成工作是一种更好的方法。



     以下为原文

  Normally, it is best to use the cal engine to acquire cal standards, because sometimes we do "secret things" to make all the calibrations perfect, and you might not know those things if you are using normal VNA sweeps to acquire calibration data. 

If you are trying to calibrate through a multiport test set and don't want to repeat the o/s/l standards, there is a better way: programatically load the terms from a calset and use the unknown thru.

If you are trying to calibrate a lot of channels at one time there is a better way: use the cal-all function.

Most of the time, letting the analyzer do the work is a better way.
