PNA N5230C无引导直通校准

嗨伙计们,当我使用E5071c进行Response Thru校准时,我可以使用跟随两个SCPI来校准S21,S12,即前进和后退(@“:SENS”+ chNum +“:CORR:COLL:THRU 1,2”);
(@“:SENS”+ chNum +“:CORR:COLL:THRU 2,1”);
但似乎我不能这样使用N5230c。
虽然“SENSe:CORRection:SFORward [:STATe]”这个SCPI命令可以设置执行校准的方向。
当我把它放在“SENS:CORR:COLL:METH TRAN1”之后它不起作用。
有人来过这个问题吗?
谢谢!

  Hi guys,

When I do Response Thru calibration using E5071c,I can use followed two SCPI to calibrate S21,S12 ,i.e.Forward and Reverse
(@":SENS" + chNum + ":CORR:COLL:THRU 1,2");
(@":SENS" + chNum + ":CORR:COLL:THRU 2,1");

But it seemed I can't do as this using N5230c.

Although "SENSe:CORRection:SFORward[:STATe]  " this SCPI command can set the direction of performed calibration. It doesn't work when I put  it after "SENS:CORR:COLL:METH TRAN1".

Is anyone come acrossed this problem?

Thanks!

我将此添加为一个新示例:未引导的THRU响应校准

>据Dr_joel说,什么时候通过校准无指导,实际上,根据我的说法,你绝不应该使用非制导校准。
您应该只使用引导校准。
当你经常导致错误时,你试图使用非制导校准是什么原因?

  > According to Dr_joel,  When do unguided thru calibration, 

Actually, according to me, you should never use unguided calibration.  You should only use guided calibration.  What is you reason for trying to use unguided calibration, when it often leads to mistakes?

Dr_joel,感谢您的帮助,在我看来,当测量只需要Trace S21或S12时,通过校准可以缩短校准时间。
我不知道术语“无引导校准”和“未知校准”之间是否存在一些区别,当我参考“PNA系列网络分析仪帮助”文档时,我对术语“校准标准”和“校准类”感到困惑。

  Dr_joel,Thanks for your help,

In my opinion,Thru calibration can shorten calibration time when only Trace S21 or S12 is needed for measument.

I don't know whether there is some distinctions between term "Unguided calibration" and "Unknown calibration" and I'm confused about term "Calibration standards" and "Calibration Class" when I refer to "PNA Series Network Analyzer Help" document.
