我有一个PNA N5224A。
是否可以在史密斯圆图上设置限制线？ 以上来自于谷歌翻译 以下为原文 I have a PNA N5224A. Is it possible to put limit lines on the Smith Chart?

不是真的。
抱歉。 我写了一个非常有限的能力程序，它将使用记忆轨迹在史密斯圆图上直观地绘制一个恒定反射圆，但它是严格的视觉（见附图）。没有任何限制的测试，没有变化与 频率。 如果你愿意，我可以提供该程序，但正如我所说，它的实用性非常有限。 以上来自于谷歌翻译 以下为原文 Not really. Sorry. I did write a very limited capability program that would use the memory trace to visually draw a constant-reflection circle on Smith Chart, but it is strictly visual (see attached pic.) There is no testing of any limit and there is no variation with frequency. I can provide that program if you want, but as I said, it is very limited in its usefulness. 附件

附加了可执行文件，但为了解决发布限制，我不得不将后缀从.exe更改为_exe。 使用前重命名。 以下是简要说明：编辑：我忘了，这已发布在我们的应用页面上：http：//na.tm.agilent.com/pna/apps/applications.html jv ========== ====================================这个程序将在PNA上绘制一个活动的视觉限制线 即使在Polar / Smith格式下也能看到的痕迹。 在这些格式中，您将看到以指定幅度值绘制的圆。 指定的值可以是dB或SWR。 它仅作为视觉限制，并不会实际测试指定的限制。 它作用于活动跟踪并将限制显示为内存跟踪; 因此，如果您还需要将内存跟踪用于其他目的（例如规范化），则无法使用此程序。 该程序的未来版本可以消除此限制。 操作很简单，如果经常使用，建议将其作为宏调用（为方便起见）。您可以将可执行文件放在PNA上的任何位置，但建议使用C： Program Files Agilent Network Analyzer Documents。 根据需要设置PNA，并确保活动迹线是您想要限制线的测量值。 运行程序。 然后，您可以根据所选的选项输入所需的任何dB或SWR值。 虽然精度限制在2或3位小数，但SWR和dB之间的切换也可以进行方便的转换。 转换的钳位频率为-199 dB，SWR为1999.点击“开始”，将显示限制线。 PNA窗口左下方将显示一个小窗口。 要更改限制，请单击“设置”。 要打开或关闭限制，请单击开/关按钮。 如果您需要更改扫描的点数，您将收到一条警告，指出内存不再有效，限制线将消失。 要使用新的点数重新显示限制，只需双击表单的空白区域（设置按钮右侧的区域）。如果用作宏，则可以指定起始值 通过以下两种样本格式之一提供运行时参数来限制行：对于-13.98dB的dB限制，使用运行时参数：/DB-13.98对于SWR限制为1.5，使用运行时参数：/ SWR1 .5当用作具有运行时参数的宏时，将立即绘制限制线，而不显示插入的设置窗口。 可根据要求提供VB6源代码。 以上来自于谷歌翻译 以下为原文 The executable is attached, but to get through the posting limitations, I had to change the suffix from .exe to _exe. Rename before using. Below are the brief instructions: Edit: I forgot, this is already posted on our apps page: http://na.tm.agilent.com/pna/apps/applications.html jv ============================================== This program will draw a visual limit line on the PNA for the active trace that can be seen even when in Polar/Smith format. In these formats, you will see a circle drawn at the magnitude value specified. The value specified can be in dB or SWR. It is intended as a visual limit only and WILL NOT actually test for the specified limit. It acts upon the active trace and displays the limit as a memory trace; therefore you cannot use this program if you also need the memory trace for other purposes, such as normalization. Future versions of this program may eliminate this limitation. Operation is simple and, if used often, it is recommended that it be called as a macro (for convenience.) You can place the executable anywhere on the PNA, although C:Program FilesAgilentNetwork AnalyzerDocuments is recommended. Setup the PNA as needed and make sure the active trace is the measurement for which you want the limit line. Run the program. You can then enter any dB or SWR values desired depending upon the selection chosen. Switching between SWR and dB will also perform a handy conversion, although accuracy is limited to 2 or 3 decimal places. Conversions are clamped at -199 dB and SWR of 1999. Click on Begin and the limit line will be displayed. A small window will be displayed on the lower left of the PNA window. To change the limit, click on Setup. To toggle the limit on or off, click on the ON/off button. If you need to change the number of points of the sweep, you will get a warning that the memory is no longer valid and the limit line will disappear. To re-display the limit using the new number of points, simply double-click on the blank area of the form (the area just to the right of the Setup button.) If used as a macro, you can specify the starting value of the limit line by providing a runtime parameter in either of these two sample formats: For a dB limit of -13.98dB, use a runtime parameter of: /DB-13.98 For a SWR limit of 1.5, use a runtime parameter of: /SWR1.5 When used as a macro with runtime parameters, the limit line is immediately drawn with no intervening Setup window shown. VB6 source code is available upon request. 附件

从功能规划的角度来看，这是一个有趣的请求。
你能详细说明你的申请和用例吗？ 以上来自于谷歌翻译 以下为原文 This is an interesting request from a feature planning stand point. Can you elaborate on your application and use case? |

Hmmmm。 我们刚刚在我们的公式编辑器中添加了一个matlab解释器（我认为它将随Dec.发布一起提供），我认为创建一个完全符合你想要的运行时matlab dll非常简单...唯一的问题是可以 我让它在传球和失败之间改变颜色......也许不是，但让我想到一些...... 以上来自于谷歌翻译 以下为原文 Hmmmm. We just added a matlab interpreter to our equation editor (I think it will ship with the Dec. release) and I think it would be really simple to create a runtime matlab dll that does exactly what you want... The only issue is can I make it change color between pass and fail...maybe not, but let me think of something.... |

Keysight：
有没有类似的东西在N9340B上测量射频通道功率图上绘制EMI限值？ 提前致谢！ 问候， 布赖恩 以上来自于谷歌翻译 以下为原文 Keysight: Is there something similar to draw EMI limits on measured RF channel power plots on the N9340B? Thanks in advance! Regards, Brian |

你在谈论N9340B上的Spectrum Emission Mask功能吗？ 如果是这样，您对PNA进行了哪些测量可能会受益于通道功率限制？ 通过PNA和PNA-X上的新SA应用选项，我们可以测量通道功率，但到目前为止，我们还没有为它添加特定的限制测试。 如果您可以详细说明您的用例，我们可以告诉您我们现有的任何功能是否可以满足您的需求。 以上来自于谷歌翻译 以下为原文 Are you talking about the Spectrum Emission Mask feature on the N9340B? If so, what measurement are you making on the PNA that might benefit from a channel power limit? With the new SA application option on PNA's and PNA-X's, we do have the ability to measure channel power, but to-date, we have not yet added a specific limit test for it. If you can elaborate a little about your use case, we can let you know if any of our existing capabilities can do what you want. |
