Correct. The EXT is nothing like an MXA, except for the processor board being similar construction but not firmware compatible.

During the transitions form HP to Agilent and Agilent to Keysight, there were short periods of time where the front panels and other places in many instruments had the new name but the software had not yet been updated with the new name in every bit of code.

The EXT wireless STATIONS ?have nothing hardware in common with the X series-besides it`` seems`` to have same processor board.If one look at EXT and MXA you see just physically they are not compatible…no way to -upgrade- an ext to? x series or the other way.
Why ??keysight tell YOU ?from your s /n you got an ext I don’t know—please let me see!!I have serviced several of these -upgraded- to ?mxa`s—all literatures.parts-list ?from agilent/keysight ?match … they are real mxa`s ….Besides one mention cpu/processor upgrade???they are all XP machines!....so no way—no more from me!
Hi Hardy. The EXT is a very similar instrument, possibly cheaper? I contacted Keysight with my serial number and it came back as an EXT so seems it has been upgraded (CPU & O.S?) to MXA. Ok some may be genuine MXAs, mine clearly is not. I don't think it matters and as mentioned I do not want to put buyers from purchasing.
