Definition of Terms
Calibration Ad
-
justment Toler-
ance: The maximum tolerated
deviation from the true 10
MHz frequency after cali-
bration. If the timebase
frequency does not ex-
ceed the tolerance limits
at the moment of calibra-
tion, an adjustment is not
necessary.
Total Uncertainty: The total possible devia
-
tion from the true 10 MHz
frequency under influence
of frequency drift due to
aging and ambient tem
-
perature variations versus
the reference tempera
-
ture. The operating tem
-
perature range and the
calibration interval are
part of this specification.
