The GUI displays a number of input fields:
 Ocean Region. Select the ocean region satellite pointed to by the monitoring antenna.
 Oscillator Frequency. Set this parameter to the frequency of the local oscillator used, or set it to
0 if an external converter or mixer is not used.
 Frequency Offset. Find out how accurately the receiver sets its frequency. Use the real-time FFT
item in the Analysis DIRECT menu and select a bandwidth of 24 kHz to find out the frequency
offset of the receiver. Adjust the receiver to the NCSC frequency of the appropriate ocean region.
Following this, the NCSC signal should be centered exactly in the FFT display. The adjustment ap-
plied to centre the NCSC signal is the offset (make it accurate to 500 Hz or less).
 L Band and C-Band Center Frequency. Exact value of the L or C-band frequency that is con-
verted to 70.000 MHz.
