Polarization - signal polarization. For linear polarization: Vertical, Horizontal. For circular polarization: Right, Left
Symbolrate - symbol rate also known as the baud rate, refers to the number of signal changes per second (1000-50000 Kbaud)
LNB (Low-Noise Block) options
LOF1 - Low sub-band, MHz
LOF2 - High sub-band, MHz
SLOF - Sub-band range. If adapter frequency more than SLOF, than will be used LOF2 value and sends tone (22 kHz) signal to LNB to switch
Force Tone - option to send 22 KHz tone signal
LNB Mode - select additional LNB modes
Default options depends on the adapter frequency:

For circular polarized converters (e.g. 36°E, 56°E), set 10750 in LOF1
LNB Polarization
The LNB polarization option controls the signal received by the satellite dish. The voltage level for LNB power supply is defined by the polarization:
13V is for Vertical/Right polarization. Switching signal in the range of 11-14 Volts
18V is for Horizontal/Left polarization. Switching signal in the range of 16-20 Volts
LNB Modes
LNB Sharing - in this mode, the LNB voltage supply and tone signal are disabled. This allows you to connect several DVB-adapters to a single converter through a passive splitter. On the splitter, only one adapter must be active; the any other adapters should be passive. All adapters on the same splitter should use the same polarization and the same sub-band (frequency greater or less than the value of slof)
DiSEqC 1.0 - digital Satellite Equipment Control is a communication protocol for use between a satellite receiver and a device such as a multi-dish switch or a small dish antenna rotor. Version 1.0 allows switching between up to 4 satellite sources
DiSEqC 1.1 - allows switching between up to 16 satellite sources
DiSEqC Command - sends a raw command to DiSEqC
Tone Burst - also known as mini DiSEqC. Allows switching between 2 satellite sources
Unicable I (EN50494) - provides simultaneous access to multiple LNBs over a single coaxial cable for several receivers. Version I provides access up to 8 satellite sources
Unicable II (EN50607) - provides access to up to 32 satellite sources
Advanced options
Modulation - method used to convert digital data into an analog signal. Default: QPSK for DVB-S, PSK8 for DVB-S2
FEC - forward error correction. Default: Auto
Roll-Off - spectrum efficiency. Only for DVB-S2. Default: 35
Stream ID - PLP stream ID for multistream transponders. Only for DVB-S2
