Generated Timecodes
Besides the amplitude modulated sine wave signal, the board also provides unmodulated
DC-Level Shift TTL output in parallel. Thus six time codes are available.
a) B002:
100pps, PWM DC signal, no carrier
BCD time of year
b) B122:
100pps, AM sine wave signal, 1 kHz carrier frequency
BCD time of year
c) B003:
100pps, PWM DC signal, no carrier
BCD time of year, SBS time of day
d) B123:
100pps, AM sine wave signal, 1 kHz carrier frequency
BCD time of year, SBS time of day
e) AFNOR:
Code according to NFS-87500, 100pps,
AM sine wave signal, 1kHz carrier frequency,
BCD time of year, complete date, SBS time-of-day,
Signal level according to NFS-87500
f)
IEEE1344:
Code according to IEEE1344-1995, 100pps,
AM sine wave signal, 1kHz carrier frequency,
BCD time-of-year, SBS time of day, IEEE1344
extensions for date, timezone, daylight-saving
and leap second in control functions (CF) segment.
