Wall Antenna

The wall antenna
antenna attaches magnetically to the mounting bracket. The cable from the antenna
is routed through a hole drilled in the wall. Coaxial cables carry signals and power
between the antenna and the IF converter, and between the IF converter and the
shelf.

Functional Description
Figure 1-6 shows the main functions of the TimeSource 3600. The center of the
TimeSource 3600 is the BesTime Ensemble Timing Generator, which uses the
BesTime algorithm to analyze the phase and frequency relationships, individually
and collectively, of the timing sources. Each type of timing source has a particular
characteristic that gives it an advantage over other sources, as listed in
The BesTime algorithm uses the best characteristic of each source to produce an
output signal with greater overall accuracy and stability than any single source. The
contribution of a source is based on its deviation from the weighted average of all
the sources. The more accurate a source, the more weight it has in the final output.
Every source is under constant evaluation and its contribution subject to periodic
adjustment. The output is essentially the best performance of each individual
source.
