4.2 IRIG-B Time Input
The recorder is equipped to handle modulated or unmodulated GPS satellite
time IRIG-B signals. The IRIG-B time signal is connected to the BNC connec-
tion on the back of the recorder. When the IRIG-B signal is provided to the re-
corder and is enabled in the settings through the user interface, the IRIG-B
functional LED comes on and the recorder clock is referenced to this signal.
No settings are required to differentiate between modulated or unmodulated
signals; this is automatically detected by the recorder.
You can enable or disable the IEEE 1344 extension in the terminal mode set-
tings
Utilities>Setup>Time . The enabled mode receives the year from the
IRIG-B signal. Disable this setting, if the available IRIG-B signal has no year
extension.
