Hi Hardy, Yes all is fine. If the buyer checks the serial number with Keysight (phone call as web app wont recognise it) you may find its not a genuine MXA. It doesnt matter as its (probably) an upgraded EXT. It doesn't really matter as long as it's working! Mine is definitely like this as it's had an upgrade and front panel label looks cheap. I think many are like this. Its not a problem and do not want to put any buyers off!
