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.
