嗨，我将验证安装在PCB上的2端口组件，并计划使用开路，短路，负载，直通和线路为PCB制作TRL套件。
从SMA连接器到组件的距离为L，因此到反射“标准”的距离为L，通过2 * L，线为2 * L + dL。 对于我之前使用的HP8510，这是标准程序。 但是，我已经意识到我现在可用的HP8753D分析仪在TRL校准方面是有限的（它有TRL *）。 使用此设备的建议方法是什么？ 我仍然可以继续使用PCB TRL套件，还是应该以其他方式完成？ 还有，有什么方法可以将修改后的校准套件保存到软盘上吗？ 我记得，这可以在HP8510上完成，但除了保存完整的状态之外，我还没有找到适用于HP8753D的任何明显的“按键按钮”。 以上来自于谷歌翻译 以下为原文 Hi, I will verify a 2-port component mounted on PCB and planned to make a TRL kit for the PCB using open, short, load, thru and line. The distance from SMA connector to the component will be L, so the distance to the reflection "standards" would be L, the thru 2*L and the line would be 2*L+dL. For the HP8510 I have used before this was the standard procedure. However, I have realised that the HP8753D analyzer that I have available now is limited when it comes to TRL calibration (it has TRL*). What is the recommended way of doing it using this equipment? Can I still pursue with the PCB TRL kit, or should it be done in an other fashion? Also, is there some way of saving a modified cal kit to the floppy disk? As I remembered, this could be done on the HP8510, but I haven't found any obvious sets of "button-pressing" that works for the HP8753D, besides saving the complete state.

我记得，这可以在HP8510上完成，但除了保存完整的状态之外，我还没有找到适用于HP8753D的任何明显的“按键按钮”。 基于20 GHz 8720D，它似乎与8753系列共享许多固件，以下内容将起作用。 1）加载用户校准套件2）关闭错误纠正 - 这可以防止它保存不必要的数据。 3）我现在不在VNA前面，所以这是来自记忆。 按Save / Recall，然后搜索“选择磁盘”。 按下并选择内部软盘4）保存状态。 它节省的很少，占用磁盘空间很小。 我认为保存的文件显示类似于FOOBAR（K）或者它可能是FOOBAR（C）两种方式，括号中只有一个东西，如果你看了屏幕，它说“K”或“C”是 校准套件定义。 如果你在括号中看到几个东西，那么它已经保存了不必要的东西。 正如我所说，这是基于我对8720D的经验，它有最新的固件，但试试我所说的，你可能会发现它做你想要的DaveEdited：drkirkby于2013年11月12日上午11:21 以上来自于谷歌翻译 以下为原文 > {quote:title=peol1 wrote:}{quote} > Also, is there some way of saving a modified cal kit to the floppy disk? As I remembered, this could be done on the HP8510, but I haven't found any obvious sets of "button-pressing" that works for the HP8753D, besides saving the complete state. Based on the 20 GHz 8720D, which seems to share a lot of the firmware with the 8753 series, the following will work. 1) Load your user cal kit 2) Turn off error correction - this prevents it saving any more data than necessary. 3) I'm not in front of the VNA now, so this is from memory. Press Save/Recall, then hunt around for "Select disk". Press that and select internal floppy 4) Save the state. It saves very little, and takes up little space on the disk. I think the file saved shows something like FOOBAR(K) or it might be FOOBAR(C) either way, there is only one thing in brackets, and if you read the screen, it says that the "K" or "C" is the cal kit definitions. If you see several things in brackets, then it has saved more than necessary. As I say, this is based on my experience with an 8720D, which has the latest firmware, but try what I said, and you might find it does what you want Dave Edited by: drkirkby on Nov 12, 2013 11:21 AM |

无论“ons”或“offs”的变体是什么，我都能使它成为“ISTATE（C）”或“ISTATE（CD）”（C = cal，D =数据），而不是ISTATE（K）（calKit）
在定义磁盘保存菜单中选择...也许它是这台机器上没有的功能... 以上来自于谷歌翻译 以下为原文 I can make it go "ISTATE(C)" or "ISTATE (CD)" (C=cal, D=data), but not ISTATE(K) (calKit), no matter what variants of "ons" or "offs" are selected in the define disk-save menu... Maybe it is a feature not available on this machine... |

Dr_Joel或其中一个安捷伦人员可能能够 给你建议。 我本以为你可以把事情带到一个状态，在这个状态下，任何被保存的东西都很小，所以没有真正的后果。 如果没有，另一个技巧可能是从安捷伦网站http://na.tm.agilent.com/pna/caldefs/stddefs.html下载8753D任何旧校准套件的定义，例如 这个文件http://na.tm.agilent.com/pna/caldefs/87xx/D53N5F.zip里面会有3个文件（我想）。 然后覆盖生成VNA的.ck文件，保持该zip文件不触及其他文件。 或者使用Cal Kit Manager 2.1编写.ck文件，再次从该zip文件中获取两个文件。 我已经完成了为8753D创建文件的技巧，即使我没有这个乐器。 然后我将该文件发送给能够阅读它的人。 戴夫 以上来自于谷歌翻译 以下为原文 > {quote:title=peol1 wrote:}{quote} > I can make it go "ISTATE(C)" or "ISTATE (CD)" (C=cal, D=data), but not ISTATE(K) (calKit), no matter what variants of "ons" or "offs" are selected in the define disk-save menu... Maybe it is a feature not available on this machine... Dr_Joel or one of the Agilent guys might be able to give you advice. I would have thought you could have got the thing to a state where whatever is saved is small, so of no real consequence. If not, another trick might be to download a definition of any old cal kit for the 8753D from the Agilent web site http://na.tm.agilent.com/pna/caldefs/stddefs.html e.g. this file http://na.tm.agilent.com/pna/caldefs/87xx/D53N5F.zip where there will be 3 files (I think). Then over-write the .ck file produced the VNA, leaving the other files untouched from that zip file untouched. Or use Cal Kit Manager 2.1 to write the .ck file, again taking two files from that zip file. I have done this trick to create a file for an 8753D, even though I did not have the instrument. I then sent that file to someone, who was able to read it. Dave |

我已经解决了cal kit的问题。
当使用预定义的校准套件时，我可能尝试保存状态。 这只给了我ISTATE（C）。 但是，如果我修改了该校准套件，请给它另一个名称并进行另一次校准，然后进行测量并在该点保存状态，结果为ISTATE（CK）。 校准套件随附保存。 因此，由于原始校准套件是在第一种情况下在机器中预定义的，所以当然不需要保存它...对第一个（也是更重要的）问题有任何评论吗？ 以上来自于谷歌翻译 以下为原文 I have resolved the cal kit thing. I probably did try to save the state when a predefined cal kit was used. That gives me only ISTATE(C). However, if I modify that cal kit, give it another name and make another calibration followed by a measurement and save state at that point, the result is ISTATE(CK). The cal kit is saved along. So since the original cal kit was predefined in the machine in the first case it didn't bother to save it of course... Any comments on the first (and more important) question? |
