Below each submenu is described:
IQ-calib
This selection will perform an IQ-calibration. When
activated, calibration might run for about 10 minutes.
While calibrating, the handset display will show “Calibrating
Wait...” and when finished the display shows “Done” and
the terminal will reset itself.
If calibration fails the display shows “Failed Try Again” for
20 seconds or until you press any key.
IQ-const:
This selection is used to read the IQ constants for
Modulator and Demodulator. The IQ-constant order is:
Iamp, Qamp, Ioff, Qoff, Phase.
MO adjust:
This selection will adjust the system Master Oscillator (MO).
Normally the MO adjustment is maintained during normal
use of the terminal. Under special conditions, e.g. system
not used for a very long time, the MO long-term drift will
prevent satellite synchronisation. This will be revealed by
an error message after power-up showing “Wait for NCS”.
This selection will readjust the MO. Fine-tuning will take
place automatically during subsequent normal use.
When adjustment is started the following list is shown:
o W-Atlantic
o E-Atlantic
o Pacific
o Indian
o Best Coice
