12.1 Programming of SAT input frequencies
For newer modules (e.g. SPM-UTCT; SPM-STCT-CI) the appropriate transponder
frequency can be entered as the input frequency.
For a few older modules, not the transponder frequency must be entered as the input
frequency of the satellite modules, but the difference between the transponder
frequency and oscillator frequency of the LNB.
12.2 Programming of DVB-C and DVB-T input frequencies
Unlike the analogue terrestrial area, the channel center frequency is entered as the
input frequency, and not the video carrier.
Example:
Channel
bandwidth
channel center frequency
Channel 24 = 494 … 502 MHz = 498 MHz
