My unit is a JD785A. From my understanding it should fall in this category "JD740B/JD780A/JD780B ?  Or I'm wrong?


nctnico:
I missed that. AFAIK the 785A falls into the 780A category indeed

giovannirat:
So I'm still not sure if I can update from my current release directly to the latest release ?  :-//

The last thing I want is a bricked device....

Any suggestions from your experience?

Thank you very much :-+

giovannirat:
Viavi technical support was very responsive.

Update to the newest release can be done, there are no dependencies.

In fact update was flawlessly, no problems..

Hello nctnico,
I am interested in your comments about the JDSU JD745A, because I am hesitating to buy this equipment (used) or an Owon XSA1036-TG (new).
My main (but not only) purpose is to use it to check gain, power and frequency response of RF amplifiers (Mobile Signal Repeaters)
I would like to know your opinion on which one is better for that and its pros & cons.
Thank you
