Hi, everyone. I have a 8753D VNA with firmware revision prior to 6.12 (it is 5.40 Mar 27, 1996).
While trying to perform a TRL* calibration, I read on the manuals that there are 3 classes for the TRL cal. But, these classes do not appear in my 8753D. There are only 12 classes instead of 15.
After downloading VNA cal kit manager, i found out that:
"The 8753D network analyzer (with firmware revision prior to 6.12) does not use the three TRL classes in implementing its TRL* calibration. Instead, it re-uses the ten reflection and transmission classes from the full two-port cal in its own unique way. It is recommended that you refer to the Agilent 8753D operating manual for instructions on how to define a TRL* cal kit and perform the calibration.
Hopefully, no one is still using this old firmware. Later revisions have added the three TRL classes."
So, I tried hard to find an older manual for 8753d, but without success..
I would really appreciate if someone could upload or give a link for an old version (probably earlier than Mar 27, 1996) of the 8753d user guide. Or, if someone could give me info about the definition of the classes for TRL* cal.
Also, the TRL/LRM OPTIONS softkey is missing from the "Modify Calibration Kit Menu", which has options for setting the reference plane to be determined either from THRU or REFLECT. So, my 8753d uses the THRU to determine the location of the reference plane, or not?
Thank you very much in advance for any info you can provide.
