I have a spectrum analyzer FIELDFOX N9935A and I am a little confused to use it. I want to use it to measure the level of decoupling / coupling on the antenna, can this be done with this spectrum analyzer?
Yes, the FieldFox N9935A is a great tool for measuring antenna coupling. I've gathered a few resources for you to look into.
For introductory information regarding the use of FieldFox for a variety of applications in cable and antenna testing, I'd recommend starting with this video series with Tony Preston. One in particular which may be of interest to you is this one about interference analysis and data recording. This series and more comes from our Keysight Handhelds Youtube channel. Note that most of those videos are using the N9912A, but the same information should also pertain to your instrument.
If you wish to dive deeper into antenna test, have a look at the wealth of information available on the resource center tab of your device's product page, or perhaps this document explaining some more of the nitty gritty details.
Of course, if you have additional questions regarding your specific application, you can always contact Keysight by dialing 1 800 829-4444. Press #, then 2 for technical support.
Hope this helps.
Just saw this question from months ago ... are you still working on this?
