Data Fields

const char * name

const char * alias

unsigned lowfreq

unsigned highfreq

unsigned rangeswitch

struct dvbsat_freqrange freqrange [2]

Detailed Description

Stores the information of a LNBf.


name long name of the LNBf type
alias short name for the LNBf type
lowfreq Low frequency Intermediate Frequency of the LNBf, in kHz
highfreq High frequency Intermediate frequency of the LNBf, in kHz
rangeswitch For LNBf that has multiple frequency ranges controlled by a voltage change, specify the start frequency where the second range will be applied.
freqrange Contains the range(s) of frequencies supported by a given LNBf.

The LNBf (low-noise block downconverter) is a type of amplifier that is installed inside the parabolic dishes. It converts the antenna signal to an Intermediate Frequency. Several Ku-band LNBf have more than one IF. The lower IF is stored at lowfreq, the higher IF at highfreq. The exact setup for those structs actually depend on the model of the LNBf, and its usage.
