Information on the decoding of the pseudo-random sequence is available in this menu.
The following texts may be displayed:
This message indicates that the system tries to achieve a coarse synchronisation. This
procedure starts after power-up or worse receiption for more than ten seconds. If the
coarse synchronisation was successfull, the receiver enters the state of fine-correlation.
The system tries to lock the received PZF as exact as possible to generate a precise time
frame. The display shows the correlation coefficient at the end of each second, which can
be up to 100%. A high value for the coefficient should be achieved by choosing a
suitable position for the antenna.
The essential part of the tracking is completed five seconds after "FC: xx%" appeared
and the generation of pulses per minute and per second starts. Tracking steps of three
microseconds are possible each second until the internal realtime clock is synchronized
(two minutes max.). Afterwards, corrections of the time frame are executed per minute
only. The direction of these steps is displayed by the characters '>' or '<' behind the digits
of the correlation coefficient.
