I am unable to download on na.support.keysight.com the cal kit standard definition files : I get an SSL error an nothing (open the firewall, clean Microsoft Edge, modifying rules for secure sites...) gives a positive result...
I have no SSL errors at the page you say - are you sure the date on your computer is right? If the date is too far out, then SSL errors will result. Anyway, the best place for cal kit files is
Keysight Cal Kit Page
On checking further, I see the webpage is using HTTP, not HTTPS, so I am guessing your browser does not like to connecting to webpages that are not encrypted. If you really can't get at it, post the cal kit you want model and VNA model, and I will attach the file. Note I don't work for Keysight, and are in the UK, so you can't blame Keysight if there's a delay.
You might find your browser has the option to allow you to connect to non-secure sites.
Thank you for quick answer ; I would like to find the copy of the LIF diskette. It is tedious to enter the various parameters of the 85056A into my 8510B and I prefer to download the data from a LIF diskette read by an external 9122D (8510B reads only LIF formated media, C accepting both systems DOS and LIF).
If I were you, I would sort out why your browser will not let you connect to an HTTP link, as despite a lot now ar HTTPS, it is far from everyone. You should be able to bypass the warning.
I can't attach the file on this forum. Keysight have disabled that.
The actual link you want is http://na.support.keysight.com/pna/caldefs/8510/CK_24MMA.5
Get yourself a unix system, use wget, and you will have no problems
[drkirkby@duck ~]$ wget http://na.support.keysight.com/pna/caldefs/8510/CK_24MMA.5

I don't know if its LIF or DOS formatted, but the "file" program on Linux just says its "data" rather than "DOS".
Can I suggest that you
1) Google Kirkby Microwave
2) Select "contact us"
3) Get the email address
drop me a private email, and I will mail you the file.
