MIDAS 4.X NMS Configuration, Rev. 6
Frequency Translation A-3
An Example Ku-Band
Carrier
The translation formulas above show the RX center frequencies of a 36 MHz transponder
at Ku-Band, L-Band, and IF. This establishes the reference points need when determining
how to set up the MIDAS system to manage the bandwidth that occupies a portion of a
transponder.
System Setup
For example, suppose you have 2.4 MHz on this
transponder that your Ku-Band RX center frequency
is 11.7325 GHz (± 1.2 MHz). This example will use a
10.75 GHz Ku-Band to L- Band LO (Low Side Injec-
tion), 1.4 x Symbol Rate carrier spacing, and a 70
MHz IF. Select System Administrator. Configure the
Satellite and Transponder in the System Administra-
tion screen as follows:
