Bit Rate
Refers to the number of bits of data transmitted over a given time period. See
also bps.

BNC
Bayonet Neill-Concelman. A type of connector featuring a locking pin on the
female end and a cut-out groove for the pin on the male end.
bps
A ratio of the number of bits of data transmitted to the number of seconds
elapsed, expressed as bits per second.
BPSK
Binary Phase Shift Keying
Buffer
In data transmission, a buffer is a temporary storage location for information
being sent or received. A buffer is usually located between two different devices
that have different abilities or speeds for handling the data.
Buffer
Overflow
Within a data buffering system, the condition occurring whenever the number of
data bits entering the buffer exceeds the data capacity of the buffer.
Buffer
Underflow
Within a data buffering system, the condition occurring whenever the number of
data bits entering the buffer is not sufficient to maintain the buffer minimum
output rate.
Built-In-Self-
Test
Evaluative procedures residing in the microcontroller which are used to provide
diagnostic information regarding its operational state.

C-Band
A portion of the electromagnetic spectrum used heavily for satellite
transmissions. The uplink frequency is at 6 GHz, and the downlink is at 4 GHz.
Traditional applications include voice communications, video conferencing, and
broadcast TV and radio.
Cable Loss
Loss of signal quality within cable, typically due to impedance as a result of
excessive cable length or material construction.
Carrier Offset
The frequency difference in Hertz measured between the programmed receive
frequency and the actual frequency received.
