This menu contains the following options:
•
Auto centre. This controls whether the Rx (Doppler) buffer is centred following an Rx
path recovery from failure.
•
Multiframe sync. This controls whether the Rx buffer should be increased so that the
buffer slip magnitude is an integral number of terrestrial multiframes when necessary,
to maintain multi-frame sync when the buffer slips.
•
Manual centre. This allows the Rx buffer to be recentred manually.
