• FRAIM: (Frequency Receiver
Autonomous Integrity Monitor).
Quality of each pilot channel.
Zero indicates the signal is
acceptable; anything above zero
indicates the signal is unaccept-
able. On power-up, 3 is the
default which will be displayed
for all pilot channels until the sys-
tem locks onto a pilot signal.
• Weight: Quality of the pilot
channels relative to each other.
The higher the percentage, the
better the signal. For example, if
pilot #8 displayed 80 percent,
and pilot #2 displayed 20 per-
cent, pilot #8 would be the bet-
ter signal. If multiple pilots are
acceptable, the TimeSource
2700 ensembles the pilots into a
single composite signal by
weighting the highest quality pilot
with the greatest weighting value.
Weighting assignments are
dynamically adjusted for changes
in pilot signal quality.
• Lock: Number of seconds since
the TimeSource 2700 acquired
lock on the pilot channel (count
stops at 10,000). Zero indicates
the system is not locked to the
pilot channel.
