specifications that came with the LNB or use the model number and brand name to

LNBF LNBF stands for a Low Noise Block-converter and Feed horn. This is quite a common
arrangement where the Feed Horn focal point that collects reflected signals from the
satellite dish is combined with the low noise block-converter into one package.
LO The Local Oscillator (LO) is a circuit that creates a tone of a very specific frequency.
These units have many applications in electronics. This important thing to remember is
that there is an LO in the LNB (Low Noise Block-converter) and it is part of the circuit
that converts the received satellite RF Frequencies to the more user friendly L-Band
Frequencies. Typical values include 9.75, 10.60, 10.75, 11.00 and 11.25 GHz for the
Ku band and 5.15 GHz for the C Band of satellite frequencies.
MAC Address The Media Access Control (MAC) address is the unique hardware address for any
piece of electronic equipment attached to a network. The MAC Address for your Novra
S300 Receiver is displayed on a sticker on the bottom of the receiver.
Mbps Mega bits per second. (Million bits per second)
MBps Mega Bytes per second. One "Byte" in computer terms is the same as 8 bits. It is often
referred to as a word.
1 Mbps = 8 Mbps = 1 million Bytes (Words) per second = 8 million bits per second.
Msps Mega symbols per second. Suppose you have four symbols, call them A, B, C & D.
Let the Symbol A represent two bits of data with the value 00.
Let B represent two bits of data with the value 01
Let C represent two bits of data with the value 10
Let D represent two bits of data with the value 11
This means that if the signals we are interested in consist of 1.0 Msps (That's 1 Million
symbols per second), and each symbol represents two bits of data, then our signal
has a data rate of 2.0 million bits per second (2.0 Mbps).
The important point to remember is that satellite systems send and receive symbols
which are then converted into data. The S300 takes the resulting data and forwards it
to your computer in bursts called "packets."
Packet A packet is the unit of data that is routed between an origin and a destination. When
any file is sent from one place to another (the Internet as an example) it is divided into
"chunks" of an efficient size for routing. Each of these packets is separately numbered
and includes the Internet address of the destination.
PID The Packet Identification Code (PID) is used by the receiver to sift through the
different packets of the transport stream. The transport stream contains data
representing many different signals. The S300 software running on your PC uses the
PID number to find only those packets of data that contain the information you have
requested. (See RF Frequency.)
Polarization, Circular In layman's terms, a circularly polarized signal corkscrews towards the earth.
(Right / Left) Unlike linear polarization (described below), where the signal is fixed in an up and
down fashion or a side to side fashion, Circular Polarization causes the signal to
rotate. If it were possible to actually see the incoming signal, it would rotate like the
hands on a clock. As with Linear Polarization, this has two modes of operation. It can
