Agilent 8563E ERR 456 AMPL
« on: January 11, 2022, 12:17:24 pm »
My Agilent 8563E developed “ERR 456 AMPL” after I dig out from storage today. Reading through the Service Guide yield no hints. All the yellow LED in A2 light up correctly which I presume all power ok.

Believe this error is related to A5 IF board but don’t know how to start the troubleshooting.

Looks like my unit is thermal related as those ERR gone away after turn on for a while  :-//. I have it turned on for few hours now and feeding it an FM modulated FM signal and everything sport on compare to another SA.
