16.6.16.2 Inverted Spectrum
Input Frequency = LO Frequency - RF Frequency
For example:
Note, The data used in this example is taken from a standard LNB.
• When using a C-band LNB with LO = 5.75 GHz and a receive band of 3.6 to 4.8 GHz, the
resulting L-band frequency (noted as the demod's "Input Frequency") will be in the range of 5.75
GHz - 3.6 GHz = 2150 MHz and 5.75 GHz - 4.8 GHz = 950 MHz.
In this case:
Input Frequency = LO Frequency - RF Frequency and the spectrum will be inverted (because the
LO is higher in frequency as the received frequency)
