怎么使用HP8753D VNA验证谐振频率

大家好，我现在有一个问题，我有一个E5062A VNA，它目前正在服务于我的目的。
但问题是我没有准确的校准套件。
它支持85033D校准。
套件和我有套件的男性版本。
现在，当我进行校准时，我需要包括一个通过连接器来获取开路，短路和负载读数。
但是在校准完成并且我正在进行测量之后，我需要从同轴电缆上取下直通连接器并读取读数。
此“直通”连接器是否会影响测量数据。
当我比较我有8753D，8720D和E5062A的3个VNA的值时，我看到8753D和8720D的值是匹配的，但是对于E5062A，值有一些不同（匹配率不如其他2个VNA那么大）
）。
是不是因为这个E系列使用了不同的套件。
因为我使用8​​5033C用于8753和8720和85033D用于E系列。
我想这应该没有任何影响，但仍然想与专家核实.. :)再次感谢您的建议。
问候

  Hi All,

I have a question now, I do have a E5062A VNA and it does currently serve my purpose. But the problem is I don't have the exact calibration kit for this. It supports a 85033D cal. kit and I have the male version of the kit. Now when I do the calibration I need to include a thru connector to take the open, short and load readings. But after the calibration is done and I am making the measurements, I need to remove the thru connector from the co-axial cables and take the readings. Does this "thru" connector affect the measurement data. When I compare the values from the 3 VNAs that I have 8753D, 8720D and E5062A I see that the values for 8753D and 8720D are matching but for E5062A there is some dissimilarity in the values (matching ratio is not as great as the other 2 VNAs).

Can it be because of the different kit used for this E series. As I am using 85033C for 8753 and 8720 and 85033D for E series. I guess this should not have any effect, but still wants to check with the experts.. :)

Thanks again for the advise.

Regards

据我所知，没有男性版本。
85033D有男性和女性部分。

只需要看一下eBay，如果你仔细观察，即使卖家没有这么说，你也会看到90％的销售都是不完整的。
我买了我所有的校准套件* 85032B（6 GHz N）* 85033E（9 GHz 3.5 mm）* 85052B（26.5 GHz 3.5 mm）* 85050B（18 GHz，APC7）使用，只有其中一个，（85033E）

所有其他部件都缺少部件和/或部件损坏。
85032B现已完成，85050B现在只是缺少连接器量具，虽然我有另一个APC7连接器量具。
85052B有很多问题，所以它完全无法使用。

它当然确实如此！
如果在校准时必须使用适配器，那么您的校准将是错误的。
因此，当您移除适配器进行测量时，您的测量结果将是错误的。
>当我比较我有8753D，8720D和E5062A的3个VNA的值时，我看到8753D和8720D的值是匹配的，但对于E5062A，值中有一些不同（匹配率不如其他2）

我想这应该没有任何影响，但仍然想与专家核实.. :)是的，它会产生影响。
如果你的固件不支持你的校准套件，那么结果将是错误的，除非你排除它。
如果您的校准套件不在VNA的固件中，您可以随时将其定义为用户校准套件。
因此，如果您有一个完整的校准套件，只需设置VNA即可使用该校准套件，并忽略仅有部件的套件。
根据我的研究成果，E5062A是ENA-L系列型号。
根据http://na.tm.agilent.com/pna/caldefs/stddefs.html，固件有85033D和85033E，而不是85033C。

我认为唯一的复杂因素是使用85033D的机器不支持它，并且没有可供下载的文件。

8753和8720D都不支持定义电感，所以应该将短路的偏移延迟稍微改变一下 - 我不确定多少，但它会很少。
如果最坏的情况发生，我可以从我的8720D中读取这些值，因为它支持固件中的85033E，看起来85033D和85033E具有相同的常数，而85033C是一个完全不同的动物，可能适用于8753

There is no male version as far as I am aware. The 85033D has both male and female parts. 

http://www.home.agilent.com/en/pd-1000000584%3Aepsg%3Apro-pn-85033D/calibration-kit-35-mm

says "The Agilent 85033D calibration kit contains fixed loads and open and short circuits in both sexes" 

Of couse, you might have some parts missing, which *very* often happens with cal kits - people lose bits. One only has to look on eBay, and if you look very carefully, you see 90% of them sold are incomplete, even if the seller does not say so. I've bought all my cal kits

* 85032B (6 GHz N)
* 85033E (9 GHz 3.5 mm)
* 85052B (26.5 GHz 3.5 mm)
* 85050B (18 GHz, APC7)

used, and only one of them, (the 85033E) was complete and working when I got it. All the others had parts missing and/or parts damaged. The 85032B is now complete, the 85050B is just missing the connector gage now, although I do have another APC7 connector gage. The 85052B has numerous issues, so it is totally unusable. 

> Now when I do the calibration I need to include a thru connector to take the open, short and load readings. But after the calibration is done and I am making the measurements, I need to remove the thru connector from the co-axial cables and take the readings. Does this "thru" connector affect the measurement data. 

Most certainly it does! If you have to use an adapter when calibrating, then your calibraiton will be wrong. So when you remove the adapter for the measurements, your mreasurements will be wrong. 

> When I compare the values from the 3 VNAs that I have 8753D, 8720D and E5062A I see that the values for 8753D and 8720D are matching but for E5062A there is some dissimilarity in the values (matching ratio is not as great as the other 2 VNAs).

That's bad, but I think you are using the wrong cal kit for the 8720. 

> Can it be because of the different kit used for this E series. As I am using 85033C for 8753 and 8720 and 85033D for E series. I guess this should not have any effect, but still wants to check with the experts.. :)

Yes, it will have an effect. 

If your firmware is not supporting the cal kit you have, then results will be wrong unless you sort that out. If you have a cal kit that is not in the firmware of the VNA, you can always define it as a user cal kit. So if you have a complete cal kit, just set up the VNA to use that cal kit, and ignore the kit for which you only have some parts. 

From what I can work out, the E5062A  is an ENA-L series model. According to 

http://na.tm.agilent.com/pna/caldefs/stddefs.html

that has in firmware both the 85033D and 85033E, not the 85033C. But from experience, I know the models of cal kits in the firmwware of the 8720D change with firmware version, so I would not totally trust 

http://na.tm.agilent.com/pna/caldefs/stddefs.html

I suspect your results on the E5062A are correct using the 85033D, and the results on the 8720D are wrong using the 85033C. It seems like the 85033C might be a *very* old kit for the 8752A and 8753. 

http://www.home.agilent.com/en/pd-85033C%3Aepsg%3Apro-pn-85033C/35mm-calibration-kit-for-8752a-8753

the manual of which is 

http://cp.literature.agilent.com/litweb/pdf/85033-90007.pdf

Looking at that I see for the opens

C0=53, C1=150, C2=0, C3=0, offset delay=14.491 ps

and for the shorts, 

offset delay = 16.695 ps. (L0, L1, L2 and L3 are assumed to be 0)

Those are very different from the 85033D kit, which has much longer offset delays, and different values for C0, C1, C2 and C3. 

You *really* need to sort out what kits your VNAs are expecting. The only complication I forsee is using an 85033D with a machine that does not support it and for which no files are available for download. The problem there is the data I can find includes the inductance values for the short - L0, L1, L2 and L3. Neither the 8753 nor the 8720D support defining an inductance, so one should shift the offset delay of the short a bit -  how much I am not sure, but it will be very little. If the worst comes to the worst, I can read those values out of my 8720D, as it supports the 85033E in firmware and it seems the 85033D and 85033E have identical constants, whereas the 85033C is a totally different animal which probably works with an 8753, but not an 8720 or ENA series machine. But you do need to check the firmware carefully for yourself.

You are out of luck there, though I think you can upgrade it a bit, but not to the latest version. 

http://na.tm.agilent.com/8720/firmware/firmware.htm

says "For upgrading the 8719/20/22D to version 6.14, order the firmware upgrade kit 08720-60168". Then to confuse matters. 

"Instruments having Firmware Revisions 6.XX or lower
must be upgraded with the 8719DU/20DU/22DU Option 000
to support Firmware Revisions 7.XX or higher."

It's not entirely clear to me whether you will be limited to versions prior to 6.14. If so, the latest is 6.12. I suspect you can put 6.14, but maybe only 6.12. You certainly wont be able to fit 7.xx with that CPU. The CPU upgrade kit is obsolete. 

I can't imagine Agilent would bring out a new CPU, and not update the major version. I suspect any 6.xx will run on the unit you have, despite the first comment on that page indicates you need to upgrade the CPU in order to use 6.14. 

> And why 8753D is taking so much time to save the data. 

Joel has told you the most likely cause - your floppy disk has "gone south" has he put it. I guess any Australians would say it has "gone north"! But basically he is saying your floppy disk needs replacing. You could look up the part number, then looks on Agilent's "find a part" and see if you can purchase a floppy disk. The service manual will probably tell you how to fit one. Or if you would rather not do it yourself, Agilent would probably do it if they have the parts. 

> Does Agilent support this firmware thing now. I do get a feeling from your post that it is no more supported but still I want to recheck with you again.

There is no offical support for the 8753 or 8720 series. But 8720 firmware can be found 

http://na.tm.agilent.com/8720/firmware/firmware.htm

and 8753 firmware here 

http://na.tm.agilent.com/8753/firmware/firmware.htm

But I suspect you need a working floppy drive in order to update the 8673 firmware. It would be most unwise to try to upgrade the firmware with a floppy disk that is dying. 

Dave

> {quote：title = saviour2009写道：} {quote}>为什么8753D花了这么多时间来保存数据。
固件版本为6.12。
但是它保存数据的速度非常慢。
100分2.5分钟，200分8分钟，400分25分钟。
有什么办法可以减少这种情况。

savior2009，因为你的8753D有固件6.12，如果你在2000年初就有了那个分析器并且想要升级你的固件那么你会有两个选择：1）你可以订购固件升级套件（有一个08753）
当时的-60xxx部件号）其中包含固件6.14的EPROM芯片（以及升级说明书）以替换您现有的固件EPROM芯片，或者2）您可以订购“Option 000”CPU
升级套件可以用更新的CPU替换你的CPU，其中固件版本（7.xx修订版）可以通过软盘驱动器上传。
这些套件都不再是安捷伦提供的，但我想我可能已经看到人们有时仍会拥有其中的一些，并将其列在eBay和雅虎留言板等旧款HP / Agilent设备上。

savior2009 since your 8753D has Firmware 6.12, if you had that analyzer back in the early 2000's and had wanted to upgrade your firmware back then, you would have had two choices:
1) You could have ordered the firmware upgrade kit (there was a 08753-60xxx part number for that back then) which consisted of just the EPROM chips with firmware 6.14 on them (and the upgrade instruction booklet) to replace your existing firmware EPROM chips with, or
2) You could have ordered the "Option 000" CPU upgrade kit which would have replaced your CPU with the newer one where the firmware revisions (the 7.xx revisions) are uploadable via the floppy drive.

Neither of those kits are any longer available from Agilent, but I think I may have seen where people sometimes still have some of those and list them for purchase on sites like eBay and the Yahoo message board for older HP/Agilent equipment.

另一种可能性是HP / Agilent Yahoo组中的某个人可能会发送必要的文件来刻录自己的6.x EPROMS。
http://www.ko4bb.com/manuals/index.php上有8753D图像，但版本号并不完全清楚，尽管我怀疑它可能是6.12。
互联网上还有其他网站，其中包含用于老式HP设备的固件集合。
将软盘驱动器固定，和/或通过GPIB与仪器通信将具有更高的优先级 - 至少对我来说是这样。

Another possibility is that someone on the HP/Agilent Yahoo group might send the necessary files to burn ones own 6.x EPROMS. There are 8753D images on http://www.ko4bb.com/manuals/index.php but it is not entirely clear the version number, although I suspect it might be 6.12. There are other sites on the internet which have collections of firmware for vintage HP equipment. 

Getting the floppy drive fixed, and/or talking to the instrument via GPIB would be of higher priority - at least they would be to me.

> {quote：title = Dr_joel写道：} {quote}>如果8720D有一个更新的CPU（或选项000），那么它可以加载支持S2P的8753ES代码。
否则，不是。
你正在运行什么rev固件。
正如我记得的那样，Rev 7.74是最新的。
Joel，我的8720D正在运行固件7.74，日期为2002年10月30日，与我相信，我认为这是最新的固件。
我看不到任何方法将.s2p文件保存到内部RAM或内部软盘。
在保存到软盘时，我有两个选项 - 文本或图形。
我找不到任何方法可以将文本更改为除.csv之外的任何其他内容，以及除了jpg以外的任何其他内容。
我查看了programmig手册，看不到任何方法来获取.s2p文件。
我编写了自己的软件来保存.s2p文件，尽管有人指出存在一个错误，即未使用的测量值应保存为-99 dB，而不是我目前的0 dB。
显然，这会使模拟器失灵。
但这只是改变C行的几行。
也许在某些时候我会坚持使用Sourceforge。
对不起，我没有看到关于Agilent VEE的优秀8753驱动程序的帖子。
正如我所写的那样，即使是我的旧版Labview，Labview也太老了。
我猜测Agilent VEE的8753驱动程序可以修改为与8720D配合使用。
我认为安捷伦论坛有点搞砸了。
*我确定当我写下我的帖子时没有看到你的帖子*我收到了在论坛上显示其他新帖子的电子邮件，但是当我在论坛上看时他们不在那里。

Joel, 

my 8720D is running firmware 7.74, dated Oct 30th 2002, which like you I believe that is the latest firmware. 

I can't see any way to save .s2p files to either the internal RAM, or the internal floppy disk. When it comes to saving to the floppy, I have two options - text or graphic. I can't find any way to change the text to anythiing other than .csv, and the grahics to anything other than jpg. 

I've looked in the programmig manual, and can't see any way to grab a .s2p file. 

I wrote my own software to save .s2p files, although as someone pointed out there is a bug in that unused measurements should be saved wtih a magnitude of -99 dB, not 0 dB as I currently have. Apparently that will screw simulators up. But that is only a few lines of C to change. Perhaps at some point I'll stick that on Sourceforge.

Sorry I did not see your post about the excellent 8753 driver for Agilent VEE. As I wrote, the Labview one was too old to work in even my old version of Labview. I'm guessing an 8753 driver for Agilent VEE could be modified to work with an 8720D. 

I think the Agilent forums are a bit screwed up at the minute. 

* I'm sure I did not see your post when I wrote mine
* I've got emails showing other new posts on the forum, but when I look on the forum they are not there.
* When trying to make posts, I've seen an error about "parent not existing"

我怀疑在USB设备只能在博物馆中找到后，GP-IB将会存在很久！
让硬件通过GPIB收集数据只需购买它。
电缆和控制器可以新买。
我自己从未使用其中一个http://prologix.biz/，但我听说他们很好。
我有一张用于GPIB的PCI卡，虽然在某些时候我希望安装Labview并使用基于以太网的GPIB控制器。
我有一个我前一段时间购买过的，但从未真正使用它。
硬件不是问题，但软件可能会出现任何问题。
我知道该仪器有一个Labview GPIB驱动程序，但它是为Labview的旧版本设计的。
我自己不是Labview用户，但我确实在Sun工作站上安装了旧版本，然后尝试安装8753驱动程序。
我发现8753驱动程序对于我的Labview版本来说太旧了，它本身就很老了。
我怀疑驱动程序可以修改为使用最新版本的Labview运行 - 事实上，如果你四处询问，你可能会发现一个运行最新Labview的驱动程序。
但是我从National Instruments网站下载的那个太老了。
你可以在这里或者在hp_agilent_equipment@yahoogroups.com上询问是否有人有最新的Labview驱动程序或其他软件来通过GPIB获取数据。
>我们不能花更多的时间来解决这个问题。
我们已经花了几天时间来解决这个问题，但还没有用。
我可以给你我写的软件，但它不会是你的快速安装。
我只用Solaris检查过它，它是命令行驱动的。
不完全是用户友好的，但它确实对我有用。
安捷伦可能会为您提供修复8753D的免费报价，因为它听起来好像有故障。
将文件保存到软盘25分钟是疯了。
尽管不受支持，但安捷伦为较旧的不支持仪器提供“尽力而为”的支持。
>除了你提到的一些事情，我已经尝试了大部分。
尝试其余的，看看Joel是否有任何建议。
但是如果你想要一个快速的解决方案，可能是雇用或购买一种新仪器。使用像我这样的旧设备存在一个问题。
如果出现问题，可能需要花费大量时间进行调试。
如果时间就是金钱，那就成了一个问题。

谢谢你的所有建议。
不用谢。
PS，我会在hp_agilent_equipment@yahoogroups.com上询问是否有其他人遇到过同样的问题。

GP-IB cables are easily available. High end instruments sold today have GP-IB. I suspect GP-IB will be around long after USB devices can only be found in museums! Getting the hardware to collect data via GPIB is just a matter of purchasing it. The cables and controller can be bought new. 

I've never used one of these myself

http://prologix.biz/

but I hear they are good. I have a PCI card I use for GPIB, although at some point I expect to install Labview and use an ethernet based GPIB controller. I have one of those I purchased some time ago, but have never actually used it. 

Hardware is not a problem, but any issues might come with software. I know there is a Labview GPIB driver for that instrument, but it was designed for a very old version of Labview. I'm not a Labview user myself, but I did install an old copy on a Sun workstation, then try to install the 8753 driver. I found the 8753 driver was too old for my version of Labview, which in itself was very old. I suspect the driver could be modified to run with a late version of Labview - in fact if you ask around, you might find a driver that runs with the latest Labview. But the one I downloaded from the National Instruments web site was too old. You could ask here, or on hp_agilent_equipment@yahoogroups.com to see if anyone has a recent Labview driver or other software to grab data over the GPIB. 

> We can't afford to spend more time on fixing this problem. We have already spent a couple of days fixing this issue, but to no use yet.

I could give you software I wrote, but it will not be a quick install for you. I've only checked it with Solaris, and it is command line driven. Not exactly user-friendly, but it does me. 

Agilent will probably give you a free quote for fixing the 8753D, since it sounds to me as if there is a fault. 25 minutes to save a file to floppy is crazy. Even though it is unsupported, Agilent offer a "best-effort" level of support on older unsupported instruments. 

> Barring a few of the things you have mentioned, I have tried most of them. 

Try the rest, and see if Joel has any suggestions. But if you want a quick solution, it might be to hire or purchase a new instrument.That's one problem with using old equipment like you and I do. If something goes wrong, it can take a lot of time to debug. If time is money, then it becomes an issue. 

> Will update you what the results are. Thanks for all the suggestions though.

You are welcome. 

PS, I would ask on hp_agilent_equipment@yahoogroups.com to see if anyone else has had the same problem.
