Outputs

The module GPS167-TC provides modulated and unmodulated (DC-Level Shift)
outputs. The format of the timecodes is illustrated in the diagramms "IRIG-" and
"AFNOR standard-format".

AM - Sine Wave Output

The amplitude-modulated carrier is available at the VG-connector pin 14a. The
carrier frequency depends on the code and has a value of 1 kHz (IRIG-B). The signal
amplitude is 3 V (MARK) and 1 V
pp
the number of MARK-amplitudes during ten carrier waves. The following agreements
are valid:
a) binary "0":
b) binary "1":
c) position-identifier:

PWM DC Output

The pulse width modulated DC signals shown in the diagramms "IRIG" and
"AFNOR standard format" are coexistent to the modulated output and is available at
the VG connector pin 13a with TTL level.
