Generated timecodes
Besides the amplitude modulated sine wave signal, the board also provides unmodulated
DC-Level Shift outputs (TTL, RS232, RS422, open drain) in parallel. Thus ten time
codes are available.
a) A002:
1000pps, PWM-DC-Signal, no carrier
BCD time of year
b) A132:
1000pps, AM-Sine wave signal, 10 kHz carrier frequency
BCD time of year
c) A003:
1000pps, PWM-DC-Signal, no carrier
BCD time of year, SBS time of day
d) A133:
1000pps, AM-Sine wave signal, 10 kHz carrier frequency
BCD time of year, SBS time of day
e) B002:
100pps, PWM-DC-Signal, no carrier
BCD time of year
f)
B122:
100pps, AM-Sine wave signal, 1 kHz carrier frequency
BCD time of year
e) B003:
100pps, PWM-DC-Signal, no carrier
BCD time of year, SBS time of day
f)
B123:
100pps, AM-Sine wave signal, 1 kHz carrier frequency
BCD time of year, SBS time of day
g) 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
h) 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.
