GPS Ageless Master Oscillator Instruction Manual 1-10
Accuracy: The 17 2/3 Hz and 33 1/3 Hz Data Sync outputs are leading
edge synchronized to within ±400 nanoseconds of the Data
Clock 1PPS output. Using the 1PPS offset command, 1PO,
the Data Clock 1PPS output can be offset from 0 to 1
second in 0.1 microsecond steps. The Data Clock 1PPS
shall be synchronized within ±500 nanoseconds of other
Master Oscillator receivers having the same 1PO offset.
The 64 kHz and 18 kHz outputs are not leading edge
synchronized.
Alarm Outputs: Major alarm relay contacts; NO, NC and common, are
provided on this connector
Optional Outputs:
Option 06, 12.8 MHz outputs, changes the 64 kHz output to
50 kHz
Option 14, CTCSS Outputs, replaces the 33-1/3 Hz and
17-2/3 Hz signals with CTCSS #1 and CTCSS #2
respectively
1.6.10 Indicator Lamps
Front panel status lamps when lit indicate the following:
Power:
Primary power source is connected and switched ON.
Tracking GPS:
Receiver is tracking at least four qualified GPS satellites.
Oscillator Locked:
Oscillator is disciplined to the received GPS signal.
Major
Alarm: Alarm condition classified as “major” is active.
Minor
Alarm: Alarm condition classified as “minor” is active.
Optional Indicators:
Receivers equipped with Option 2, Internal Battery Backup,
include indicator lamps to communicate battery status:
Ready, Charging, and Replace.
1.6.11 Alarms
Alarm relays allow remote monitoring of operational status. Relay contacts are provided
for Major Alarms and Minor Alarms. Alarm status is also included in performance and
status logs obtained using software commands.
