When a satellite rotates around Earth at the same rate it rotates giving it a "fixed" location in the sky from a ground station.
What is Geo-Synchronous Orbit?
100
This device amplifies the signal and downconverts it to L-Band.
What is the LNB
100
This light blinks when it has Rx Lock and is lit solid when it has Tx Lock.

Direction the trailer is facing when setting up.
What is the equator?
200
Type of polarization used in Ka frequency band.
What is Circular?
200
This device displays the signal in a graph format, power by frequency, for the purpose of analysis.
What is spectrum analyzer?
200
Direct connections between Traffic Terminals (TTs) in the Linkway network allowing the passage of data communications without the need for Hub-routing.
What are Permanent Virtual Circuit (PVC)?
200
Located in the IFSPU, this device is set in the M&C software to 0 db every time the system is powered up.
What is the Mini-Circuits Attenuator?
200
The default configuration you want to set your spectrum analyzer to whenever it is turned on.
What is factory preset?
300
Varying one or more properties of a medium to encode information onto it.
What is modulation?
300
This device is utilized to manipulate the direction of the antenna.
What is Antenna Control Unit (ACU)?
300
This burst begins network synchronization, establishes a timing reference, and tells traffic terminals when the Acquisition Burst slots are.
What is the Reference Burst?
300
The menu option in Hyperterminal to load the bootfile into the Linkway modem.
What is Send Text File?
300
Used to configure the FDMA modem and get satellite information.
What is Satellite Access Authorization (SAA) or a cutsheet?
400
Three bits of data are represented per symbol in this type of modulation.
What is 8PSK?
400
This device is connects nearly all equipment to the laptop for monitor and control.
What is the Systec Port Server?
400
Representation of signal quality by dividing the number of error bits received by the total amount of bits received.
What is Bit Error Rate (BER)?
400
The frequency entered into the Linkway modem when the SAT controller gives you a frequency of 14.32175 GHz during peak and poll.
What is 1271750000 (1.27175 GHz)?
400

What is beacon frequency?
500
Wavelength is calculated this way.
What is Speed of Light divided by frequency?
500
In the IFSPU, this device allows inputted signals to be sent up to the HPA and LNB, but doesn't send those same signals to the modems.
What is the Diplexer?
500
The Linkway modem is considered transmit sync'd when three of these bursts are received in the correct time slots.
What is the Acquisition Burst?
500
The receive IF frequency of the transmitted IF frequency of 1150 MHz.
What is 1150 MHz?
500
RxRFFreq field in the bootfile tells the modem to find this.
