Glossary
A
Active Entry The currently selected, and therefore editable, entry or parameter
ARB Arbitrary waveform generator
Avionics Avionics is a term used to describe the electronic instrumentation on aircraft.
AWG Arbitrary waveform generator. Additive white Gaussian noise
B
BBG Media Baseband generator media. Volatile memory, where waveform files are played or
edited.
BNC Connector Bayonet Neill-Concelman connector. A type of RF connector used to terminate
coaxial cable.
C
CCW Counterclockwise
C/N Carrier-to-noise ratio
CW Continuous wave. Clockwise
D
DHCP Dynamic host communication protocol
Dwell Time In a step sweep (see page 63), the time that the signal is settled and you can make a
measurement before the sweep moves to the next point.
E
EVM Error vector magnitude; the magnitude of the vector difference at a given instant between the
ideal reference signal and the measured signal.
F
Filter factor Alpha The filter’s alpha coefficient. It is only valid for root Nyquist and Nyquist filters.
Filter Factor BbT The filter’s bandwidth-bit-time (BbT). It is only valid for a Gaussian filter (similar
to alpha). BbT is defined by the GSM standard as 0.3 and by the DECT standard as 0.5.
