Mod 9-1a

The feed horn is also capable of adjusting for different types of polarization.

What does the second number indicate during FEC rate (e.g 3/4)

It's job is to convert the digital data to usable electromagnetic waves during transmit and receive.

Used for transmitting and receiving microwave frequencies to and from space

FEC works by adding an artificial redundancy to a data stream and uses this redundancy to fix error.

Data Terminal Equipment (DTE) sends info to the modem, this inform will be in a digital format and is known as ___.

When receiving downlink from a satellite, the signal will reflect off the parabolic dish into the where?

The word that stands for modulate-demodulate.

The size of the parabolic reflector is ___ proportionate to the frequency that is being used.

A reflector is comprised of a parabolic dish of some varying size reflector

Uses mathematical algorithms to protectinformation using either a pre-shared key or a public/private relationship.

An antenna that offers conveying of signals to and from the dish, often attached to waveguides.

During linear polarization, the feed horn can be adjusted to which two polarizations.

Other antennas, results in a much higher gain than a parabolic.

After multiple copies of a message are sent to the the receiving end,it will take the multiple copies and recreate a __

Due to its grounded outer conducting shield & inner conductor this product it lessvulnerable to EMI, ideal for SATCOM.

Process of Randomizing Data.

If you are switching from X-band to Ka-band, you DO NOT have to switch out the feed horn to match.

The general purpose of a ___ is to deliver signals between the transmitter/receiver and the parabolic dish.

How many access methods are modems capable of using?

During circular polarization, the feed horn can be adjusted to which two polarizations.

During transmit operations the signal will leave the feed horn and ___, focusing it into a concentrated beam.

The FEC rate will determine the number of copies to be sent.

Assists with the sub-optimal signal-to-noise level often received at the modem.
