Time Code Output IRIG-B120 w/ IEEE1344
The selectable Code output has an additional selection for IRIG-B-120 w/ IEEE1344. Configuration is via
the Keypad / Display, RS232/422 and the Network port via telnet and HTML.
IRIG-B-120 IS DEFINED IN IRIG STANDARD 200-04 AS:
• Format B 100 pps
• 1 = Sine wave amplitude modulated
• 2 = 1KHz carrier/1mSec resolution
• 0 = BCD TOY,CF,SBS
IEEE1344 IS DEFINED IN IEEE1344-1995(R2001) ANNEX F AS:
IRIG-B format, <sync>SS:MM:HH:DDD<control bits> <binary seconds>
where
<sync> is the on time marker
SS seconds 00-59 (60 during leap seconds)
MM minutes 00-59
HH hour of day 00-23
DDD day of year 001-366
<control> 27 binary control characters, see Table 1 (reference IEEE1344)
<binary seconds> binary seconds of day
