IFR COM-120A need help
« on: September 15, 2014, 02:49:56 am »
hello everyone,this is my first topic here.
I have an IFR COM-120A service monitor,now the"deviation meter"failed in self-test.And I tried to replace most of capacitors on "BASEBAND TRAY"but it still failed.
Another problem is it had OPTIONS "OUTPUT AMP"in menu,so in operation it display AUX port can output +13DBm max,but I check infact no hardware OUTPUT AMP module in it,so if AUX out level less than-13DBm,no problem;but up to -13DBm,actual output is -13-26(amp gain)=-39DBm,oh my good....
so does anyone know.....
the calibration password of it??It calibration out of date.I don't know if re-calibration maybe OK.
and how can I cancel the option in menu?(maybe this CONTROLLER TRAY was replaced by others,not matched the machine)
I'm looking forward to someone can tell me,thanks.
