Description
.
GPS
û
ü
The Global
Positioning System
(GPS), as a source
of accurate
time, requires
an external GPS
antenna input to
provide accurate
time signals
comparable
to 500 ns. The
RUGGEDCOM
RSG2288 can use
the GPS receiver
on the PTP module
to provide the
time base for the
system.
IRIG-B PWM
û
ü
IRIG-B time
synchronization
is an even older,
established,
inter-device time
synchronization
mechanism
providing
accuracy in sub-
milliseconds.
IRIG-B AM OUT
û
ü
AM (Amplitude
Modulation)
OUT outputs IRIG
Standard 200-04
compliant signals
to synchronized
external devices.
PPx (Configurable PPS)
û
ü
PPx provides a
generic pulse
per X second
to sychronize
external devices.
