: Master IRIG-B Generator
The hardware consists of an IRIG-B generator, time and date reference in/outputs as well as
some general purpose interfaces (GPI), which may be used for various applications. The
module outputs various real-time signals: IRIG-B, impulse time telegram, time and date serial
data string. All output signals are PPS locked.
