Chapter 5 Downlink/L-Band Frequency Conversion Tables - Motorola DSR-6403 Operator's Manual

A distributor or programmer can provide the latest L-band frequency plans at purchase time. Use the
formulas in Table 5-1 and Table 5-2 to perform calculations for both C-band and Ku-band transponders,
or for installing a new satellite.
Table 5-1: Calculation for C-Band Transponders (Using 3,740 MHz Downlink Frequency)
Formula for converting a C-band Frequency to an L-band Frequency
5,150 MHz <minus> Frequency Downlink (DL) <equals> Frequency (L-band)
Table 5-2: Calculation for Ku-Band Transponders (Using 12,019 MHz Downlink Frequency)
Formula for converting a Ku-band Frequency to an L-band Frequency
Frequency Downlink (DL) <minus> 10,750 MHz <equals> Frequency (L-band)
