For basic information about the IRIG time codes standard, please refer to the
CMIRIG-B Reference Manual or the Test Universe Help. Detailed information
about the IRIG-B standard can be found, for example, in the IRIG SERIAL TIME
CODE FORMATS publication at the url https://wsmrc2vger.wsmr.army.mil/
rcc/manuals/200-04/index.html.
For detailed information about the OMICRON CMIRIG-B interface unit please
refer to the CMIRIG-B Reference Manual.
Detailed information about how to configure the Test Universe software
component Time Trigger Configuration for the use of CMIRIG-B with or
without CMGPS can be found in the CMIRIG-B Reference Manual and in the
Test Universe Help, topics Time Trigger Configuration and Hardware
Configuration (IRIG-B & GPS tab).
