Does anyone have at least typical standard definitions disk files for 8722ES analyzer? I'm looking for files to K11644A and R11644A waveguide kits which should work with 40GHz 8722ES VNA. K11644A and R11644A user manuals has only tables for 8510 and PNA series analyzer.
I downloaded those definiton files and it seems that K11644A (18GHz-26.5Ghz) works perfectly. R11644A files works too, but instrument state is wrong. After loading, 8722ES start and stop frequencies are strangely 20.5GHz. Is it fine, if i modify intrument state file and set start freq to 26.5GHz and stop freq to 40GHz?
Definitions seems to work now someway, but if i want make 2-port TRL calibration it propose me to use sliding loads when i select Line/Match option, why so? If i have understood right Line/Match should make thru measurement and inform me to put 1/4 shim between port 1 and port 2.
One another thing. Why R-kit not include anykind of waveguide to 2.4mm Coaxial adapters? Without those test port adapters kit is useless. I know, that proper adapters can buy separetly like Agilent R281A and R281B but userguide not speak anything from them.
If someone has made definition files (K and R kits) for 8722ES model. Plese let me know.
The waveguide kits <26GHz (X,P,K11644A) do include adapters. None of the higher frequency kits include adapters - I am not sure why...
The WG cal kits contain hardware that can be used for either SOLT or TRL/TRM calibrations.
The kit definitions for 8720-series analyzers are set up for SOLT calibrations. There are reasons for this: First, standard 8720 analyzers do not have the 4 receivers needed for a true TRL/LRM type calibration - they use "TRL*" which makes some assumptions that can compromise results. So, SOLT usually works better for a standard 8720 analyzer. Second, 8720 analyzers have a firmware limitation - it is not practical to combine SOLT and TRL calibrations in a single definition. see here for more info: http://na.tm.agilent.com/vnahelp/tip17.html
Now, there was an option (option 400 and some other Hxx specials) that gave you the hardware to perform a "true" TRL calibration. If you have this option on your analyzer, you might want a different cal kit definition for TRL.
I don't have these set up for all the kits. I do have a TRL definition for the X11644A WR90 kit. See the .zip file attached to this message. Use this as an example. I don't have access to an 8722 here, so I can't set up the higher frequency kits for you. But it is not that big a job - you just need to rearrange the class assignments to make TRL work.
Note that the current PNA or ENA analyzers do not have either the hardware OR the firmware limitation.
