The last of our 8510 VNAs (with the 8mm tape drives) just died, and now we have this Calibration Kit as a "spare". Problem is the calibration data is on a tape drive, not a 3.5" floppy. We'd like to be able to use it with our other 8510B's and 8510C's.

Does anyone have access to the *.ckt or *.ckm file for this kit, that we can use with the "Cal Kit Editor" software to re-generate calibration constants?

Software and Calibration Kit listings are here: http://na.support.keysight.com/pna/caldefs/stddefs.html

Thanks, ~Dan

Correct Answer

Contacted Keysight support, they sent me the correct file for this Cal Kit. Hopefully the Website will be updated at some point?

Edit - I have attached the files sent to me.

Don't have a cal kit file, but perhaps you can edit the 85054D to create an A? I don't know the history of the cal kit and didn't compare part # to part #, but the values could be similar.

  Our Calibration Lab is currently trying to do exactly that. However, they have some concerns about traceability on the standards...finding this file would alleviate those concerns.
  
  I'd prefer to just get the correct file, or enough of it (based on our part numbers/serials) to ensure a good set to load into the VNA going forward.
  
  Thanks

I can't seem to work out how to attach a file to this forum now, but I put a copy of the HP 85054A manual here

http://www.kirkbymicrowave.co.uk/HP-Agilent-Keysight-manuals/VNA-Calibration-kits/HP-85054A-calibration-kit-manual.pdf

One of the Agilent employees dug this out for me a few years ago, in reference to a question of mine about using an 85032B 6 GHz cal kit at a higher frequency.

Note the 85054A is nothing like the 85054B or D, but is very similar to the 6 GHz 85032B. I believe the open standards are the same as an 85032B, but have different coefficients, which are obviously designed to work to 18 GHz, not 6 GHz. The short standards are different to those of the 85032B.

    At one time one could, attach files to these forums, but I can't work out how to do it now. One can insert images, but I can't see a way to attach a pdf file.
    
    The forums are 10 dB harder to use than they were a couple of years ago.

        I see you are a "Community Manager", so I guess you have some influence over the forums, or can at least put your comments to the right person. I have a few comments about these forums. Hopefully it can be considered "constructive criticism".
        
        Usability.
        There was a comment on the HP/Agilent Yahoo group the other week, which read
        
        "I should check the Keysight forum more often, but the kept changing it so much that I have pretty much given up on it. "
        
        That was by one of your own members of staff. He is obviously somewhat frustrated with the forums, and so am I. I used to be regular contributor, but they forums have got more and more difficult to use. Some example issues are:

        Questions which have been asked in the past, no longer exist. For example <pre>http://www.keysight.com/owc_discussions/thread.jspa?messageID=118248&#118248</pre> which did at one point exist, now points to News | Keysight Community.

        Here are some that have no answer, but are "assumed answered"
        
        Use of 16047A to measure inductance
        Issues with LCR not Multimeters!
        Is there any standard file format for saving data from LCR meters?
        
        All of them relate to the use of LCR meters, which brings me to my next point.
        
        LCR meter and impedance analyzer forums.
        There are no forums for LCR meters or impedance analyzers. Keysight have a range of such instruments for both bench-top and handheld use, as well as a lot of fixtures for these. But there's no forum to ask about them. I believe these are developed in Japan, not the USA, and it seems the Japanese do not answer questions on forums.
        
        Back in 2015 I created a Keysight Service Request - 1-6531545249 about the lack of any LCR meter and impedance analyzer forums. I got a response which read
        
        "We will consider to create a forum related to DT products (impedance analyzers and LCR meters). At this moment, we suggest the customer to use TCC, support node or network analyzer forum until the forum for DT products is ready."
        
        Is there any good reason there are no forums for such matters?
        
        Google struggles to find things on the forums.
        Google struggles to find things on the forums, which I know have been posted. For example, the following text
        
        someones idea of a good condition calibration kit
        
        get no kits via Google, irrespective of whether quotes are used or not. Yet those exact phase appears on your site
        
        Funny (except for me) - someones idea of a good condition calibration kit.
        
        No forum to report forum issues.
        There used to be a forum where you could ask the admins questions. It was pretty useless, as rarely did anyone answer, but at least it was there. Now there is not even that.
        
        SUMMARY
        There are numerous problems with the forums, which seem to have got worst over the last couple of years. Try comparing it to some non-commercial sites.
        
        Forum for Electronics
        Linux Forums
        
        and the Keysight ones seem 100 dB worst.

        Hi -
        Thanks for your response. I indeed take it as constructive criticism and appreciate your honesty. Let me see if I can respond to a few of your issues.
        
        1. We recently decided to migrate off the previous forum platform because it was so outdated. We couldn't add any enhancements or make improvements because the tool was no longer supported. Most threads were going unanswered and there was very low participation and activity in the forums. We moved to an industry standard platform that has a more modern look and feel, could include private groups, capability for blogging and other improvements that our previous forum platform didn't allow. I understand that the current implementation isn't perfect but it is certainly better than what we had previously. It does take some time to get used to a new tool.
        
        2. I agree your "member since" data is incorrect and I will submit a bug report on this issue.
        
        3. We had to decommission the previous forum so urls you may have bookmarked from there will no longer function (that includes anything with "/owc_discussions/" in the url). We did a manual clean-up within the forums to update all urls with this syntax and redirect them to the correct thread. There may be a few that were missed. I will look into that to get them updated, but I'm sure it is very few.
        
        4. We migrated all old posts from our previous platform into the Answered Questions area. There are many posts there that are not answered. The reason we did this was so the forum moderators, Keysight employees and Community users could focus attention on new forum posts that need input and response. Older posts can still have comments added even though they are marked as answered. We chose this approach rather than lose all the older threads we had in our forums.
        
        5. I will look into adding an LCR meter forum but won't make any promises. I don't have a good reason one doesn't exist.
        
        6. The Google/SEO capabilities of this platform is exponentially improved over our previous platform.
        
        7. There is an area to ask for help, provide suggestions, etc on our Help page. Just select "Help" in the navigation and in the upper right of that page is a Question box. You can ask questions to admins there or provide suggestions for improvement. I guarantee that area of the site to be monitored and questions will be addressed, unlike the past forums where, as you mentioned, admin questions were unanswered and not monitored.
        
        I hope that helps. I know the platform isn't perfect but please continue to participate in our Community and provide suggestions. This way we can work together to make it a great place for Keysight and our customers to collaborate.
        
        Best regards,
        Jill

        Hi Jill,
        I understand the problem with lack of support on the old forums. Perhaps Keysight should have used an open-source version. At least Keysight can pay someone to add what functionality they want.
        
        I'm not worried when the forum thinks I registered, but it would be nice if I could find posts I have made. Only a very small subset are available. Perhaps only those since I supposedly registered.
        
        I tested the links for a number of treads stored in my inbox with "/owc_discussions/" in the URL. The first 3 I tried were all broken. Here are two.
        
        "The 85033E 3.5 m cal kit has no sliding load. So why offer it during cal?"
        http://www.home.agilent.com/owc_discussions/thread.jspa?threadID=34008
        
        "How NOT to package a VNA and S-paramter test set"
        http://www.home.agilent.com/owc_discussions/thread.jspa?threadID=33979
        does not link properly, but the correct URL is How NOT to package a VNA and S-paramter test set
        (Found with the aid of Google)
        
        My own perception is that Google has more struggle with the forums than it ever did, but I have no data to back that up.
        
        I know the W3C validator
        The W3C Markup Validation Service
        is not god, but I find it quite useful to check the HTML of sites I create. It finds 86 errors in the https://community.keysight.com/ page - see
        
        Showing results for https://community.keysight.com/ - Nu Html Checker
        
        If the site is littered with HTML errors, that can reduce the chances of it being indexed properly.
        
        The lack of an LCR meter and impedance analyzer forum is what I feel is very annoying. People tend to ask in the RF network analyzer forum, but rarely get the answers they want, as the staff from Japan rarely read the forums. There have been other complaints from other people about the lack of the LCR meter forums. They were in the forum for admins, which as you acknowledge were not monitored much.
        
        Anyway Jill, thanks for your help. It seems you are at least aware of some of the issues, and are working on resolving them, so hopefully the forums will get better with time.

        Hi Dave -
        The old urls with "owc_discussions" will not work. All of those threads are contained in our new forum because we migrated ALL of the content from our previous forums. But we had to decommission the previous platform so those urls will not result in a web page. You can find old threads via search within the Community or go to your profile and click on the "content" tab where you can see all your old postings. There you will notice the old postings have incorrect "Latest Activity" dates but if you click into the threads you can see the date of the original post. This is a side affect of the migration but the content is still there associated with the correct user.
        
        Also, the issue related to the "member since" data being incorrect is a known bug but I don't have an estimated fix date. Appreciate you highlighting the issue and I will continue to push for resolution.
        
        Thanks again for your insights.
        Best regards,
        Jill
