Input
Frequencies
used for TB
Calibration:
1.0, 1.544, 2.048, 5.0 or
10.0 MHz
Definition of Terms
Calibration The maximum tolerated
Adjustment deviationfrom the true 10
Tolerance: MHz 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.
