Description This function effects the tuning of the IBR-L (if fitted) to the
beacon frequency of the satellite to be tracked.
The IBR-L operates over the frequency range 945MHz to
1.75GHz (L-band). A block down converter is required to
convert the actual beacon frequency to the L-band range.
Note The conversion from the operating frequency to the L-band
frequency for the IBR-L is performed automatically for BDCs
with standard local oscillator frequencies.
Setting Frequency Menu Key 6 (Next Field) selects either the Frequency or Band
No. for editing. The Band No. must be set first otherwise the
frequency cannot be entered.
Use the numeric keypad to overwrite the band number and/or
frequency as required.
The down conversions assumed by the INTRAC-305 are :-
Band No. Conversion
1 none
2 5.15GHz - C band
3 X band - 6.3GHz
4 Ku1 band - 10GHz
5 Ku2 band - 10.75GHz
6 Ku3 band - 11.475GHZ
7 Ku4 band - 11.3GHZ
Notes Whilst bands 6 & 7 cover, in part, the same frequency range
the down conversion frequency is different.
To use an X-band frequency below 7.25GHz an IBR-L with an
extended low frequency range is required.
