源功率校准选项怎么调整

我也找不到这个命令，我写了文档。
但源功率校准选项对话框在引导功率校准中不可用，因此不在Cal All会话中。
但是，“使用功率计一次，然后使用PNA参考接收器”选项始终用于引导功率校准。
所以你的问题（'使用功率计的命令在哪里'是一个很好的问题，我将继续研究它。
请等待......

  I am also having trouble finding this command, and I wrote the documentation. But the Source Power Cal Options dialog is NOT available in a Guided Power Cal, and therefore, not in a Cal All session. However, the "Use a power meter once, then use the PNA reference receiver" selection is always used in a Guided Power Cal. So your question ('where is the command for Use the power meter at') is a good one, and I am continuing to look into it. Please stand by...

固件中确实缺少该设置的SCPI和COM实现。
我们将尝试将其纳入下一个版本，但这可能需要一段时间。
坦率地说，我甚至不确定该设置是什么，因为对话框帮助中缺少帮助文本。
希望这里的专家之一能够知道并能够为您的计划建议解决方法。
抱歉给你带来不便。

  The SCPI and COM implementation for that setting is indeed missing from the firmware. We will try to get that into the next release, but that may take awhile. 
Frankly, I am not even sure what that setting does, as the help text is missing from the dialog box help. Hopefully, one of the experts here will know and be able to suggest a workaround for your program. Sorry for the inconvenience.

你考虑过使用引导功率校准吗？
它通常更好，可以提供您需要的设置。
要打开引导功率校准的功率部分，请选中“校准源和接收器”框，然后执行包含您感兴趣的端口的校准。它通常会提示您进行2端口校准（但您可以
只做增强响应或响应）它将调整所有源和接收器以及S参数。

  have you considered using the guided power calibration? It is usually better and can provide the settings that you need.  

To turn on the power portion of guided power calibration, check the box that says "calibrate source and receiver" and do a calibration that includes the port you are interested in.

It will normally prompt you for a 2-port calibration (but you can do enhanced response or response only) and it will callibration all the sources and the receivers as well as the S-parameters.

要迁移，sourceId：109304

Joel / bhoktan博士，我需要使用Cal All功能而不是Guided Calibration，因为我有大约80个以上的通道进行校准，每个通道都有独特的频率设置。
引导校准会导致功率计插入，然后为每个通道插入ECal。
Cal All功能允许我使用单个功率计/ ECal插入完成所有这些，而不是80次插入。
您都提到了设置源功率校准的目标功率级别的命令。
我正在寻找“使用0.00 dBm功率计”对话框中的命令，该命令与“使用功率计一次，然后使用PNA参考接收器”功能一起使用。
我发现“使用功率计一次，然后使用PNA参考接收器”可以用被取代的（过时的，但仍然是一个好的）命令[SOURce：POWer：CORRection：COLLect：METHod]命令。
但是它并没有改变对话框中的设置，但好消息是它确实影响了校准的工作方式。
它设置了用于执行源功率校准的方法，在这种情况下：“PMReceiver” - 第一次迭代的功率计;
然后在必要时使用参考接收器获取剩余读数（与在对话框中选中的“快速迭代”框相同）。
安捷伦的代表声称这是使用PNA / PNA-X设置绝对输入和输出功率水平的最准确方法。
如果我使用能够处理-20到-70 dBm范围的8487D功率计，则最准确的是-30 dBm。
这是我需要在“使用功率计X.XX dBm”设置中设置的初始功率水平。
建立此锚点后，PNA可以使用[SYSTem：CALibrate：ALL：PORT：SOURce：POWer：VALue]命令准确地执行相对转换到更低的目标功率级别。
谢谢你的讨论。
非常感谢。
最好的问候，查尔斯

  Dr Joel / bhoktan,

I need to use the Cal All feature instead of the Guided Calibration, because I have about 80+ channels to calibrate, each with unique frequency settings. Guided Calibrations cause a power meter insertion followed by an ECal insertion for each channel.  The Cal All feature allows me to accomplish all this with a single power meter / ECal insertion, instead of 80+ insertions.

You both mention the command that sets the target power level for the source power calibration.  I am looking for the command in the dialog box "Use the power meter at 0.00 dBm" that works in conjunction with the in the "Use the power meter once, then use the PNA reference receiver" feature.

I found the "Use the power meter once, then use the PNA reference receiver" can be commanded with the superseded (obsolete, but still a goodie) command [SOURce:POWer:CORRection:COLLect:METHod ].  However it does not change the setting in the dialog box, but the good news is it does impact the way the calibration works.  It sets the method used to perform a source power calibration, in this case: "PMReceiver" - Power meter for the first iteration; then use the reference receiver for remaining readings if necessary (same as "fast iteration" box checked on dialog box).

Representatives at Agilent claim this is the most accurate way to set absolute input and output power levels with the PNA / PNA-X.  If I use a 8487D power meter, which can handle a range of -20 to -70 dBm, it is most accurate that -30 dBm.  That is the initial power level I need to set in the "Use the power meter at X.XX dBm" setting.  After establishing this anchor point, the PNA can accurately perform a relative shift to an even lower target power level using the [SYSTem:CALibrate:ALL:PORT:SOURce:POWer:VALue ] command.

Thanks for the discussion. It is greatly appreciated.

Best regards,
Charles

Cal-All总是使用“使用功率计一次，然后使用PNA参考接收器”方法，无论您使用[SOURce：PORER：CORRection：COLLect：METHod]命令设置什么。
当你自己做一个源功率校准时，你需要选择仅进行功率计采集，因为你可能正在校准一个没有路由到参考接收器的源，但在Cal-All中我们只校准一个
源端口，我们知道它可以用参考接收器测量，因此不需要有选项。

Actually if you are using Cal-All, then there is no option for setting the power measurement collection method.  Cal-All ALWAYS will use "Use the power meter once, then use the PNA reference receiver" method regardless of what you set with the  [SOURce:POWer:CORRection:COLLect:METHod ] command.  when you are doing a source power cal by itself, then you need the option of doing a power meter only acquisition, because you may be calibrating a source that does not get routed to a reference receiver, but in Cal-All we only calibrate one source port and we know that it can be measured with the reference receiver, so there is no need to have an option.
