IRIG Control Function (CF) Bits In the following tables, tq1 through tq4 are time quality bits. For time
quality and unlock bits, "1" means active.
For IRIG output codes A, B, E or G with CF bits, the following CF bits are encoded:
Index Bit
count name
----- -----
70 (0)
71 (0)
72 (0)
73 unlock (1 = unit not locked to reference)
74 (0)
75 tq1 (1 = timing error estimate > 1us)
76 tq2 (1 = timing error estimate > 10us)
77 tq3 (1 = timing error estimate > 100us)
78 tq4 (1 = timing error estimate > 1ms)
