I have a N9010A Spectrum Analyzer. It has almost 4 years and it's the second time I have this problem. The first one I sent it to the service, it was repaired and it has functioned fine till a month ago (almost one year and a half past the repairment).
Now the same problem: and erron occuring just after the instrument start up: "Aling now all required".
Aligning all automatically but also manually the error is still present.
How can I solve it? It's a software problem or hardware? If hardware, this device is so frail?
Thanks for help!
