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