BER Test
- In generate mode, the analyzer
modulates the RF carrier with Bit Error Rate test
pattern to test the radio receiver. This BER test
pattern consists of a free running, unframed
pseudo-random bit pattern. In monitor mode, the
analyzer monitors the BER test pattern input and
provides a metering display of bits received,
number of bits expected, and bit error rate
percentage.
Cipher
- to convert information to a seemingly
random pattern for transmission or wireline
delivery in order to protect sensitive information.
Ciphered voice and data can only be understood by
means of a special key.
CVSD Modulation
- Continuously-Variable-Slope
Delta technique used in SECURENET radios and
test equipment to digitize analog signals before
transmission and to reconstruct analog signals on
the receiving end.
Decryption
- process of converting cipher text to
plain text
Encryption
- process of converting plain text to
cipher text
EOM Signal
- A short signal burst identifying the
End-Of-Message. SECURENET radios transmit (or
receive) an EOM signal at the end of all private
mode transmissions. The signal burst lasts for at
least 140 milliseconds.
Key
- a sequence of bits stored electronically in the
encryption and decryption modules. Once the key
has been loaded, it trains the internal
encyption/decryption circuits.
Key Inserter
- a device used to load an electronic
encryption key into a radio or other device. Also
called a keyloader.
