Glossary: List of the Often Used Terms and
Abbreviations
A
Advanced mode: This term is used as an abbreviation of the "System Configuration >
Mode > Advanced". This mode is available in instruments equipped with some required
hardware and software options, like up to 4xR&S SMW-B14 and the R&S SMW-K74.
The advanced mode extends the Standard mode with MIMO configurations like 2x2
MIMO, higher-order MIMO modes (e.g. 4x4, 2x8 and 8x2 MIMO), or multiple entity
modes (e.g. 2x2x2 or 8x1x1 configurations).
B
Base unit: This term describes a R&S SMW equipped with the options R&S SMW-
B10, R&S SMW-B13 and R&S SMW-B1003.
Baseband: The baseband signal, i.e. the I/Q stream at the output of the "Baseband"
block.
In rear cases, the term Baseband is used as abbreviation of a "Baseband" block itself.
Baseband domain: A common term for signal processing up to the I/Q modulation.
The signal in the baseband domain of the R&S SMW is digital.
Baseband(s) Signal: Baseband
BBMM: Short designation of the Baseband Main Module (the bottommost board on the
rear panel of the R&S SMW).
Beamforming: Steering a beam in the direction of the receiver, e.g. UE
BS: Basestation
C
Channel (Digital Input, Digital Output): The signal provided at a digital interface con-
nector or the output stream at the digital output interface may consist of several multi-
plexed channels. Do not mistake the term channel used here with the terms Fading
channel or signal path.
A digital channel is a part of an I/Q stream.
Clock: A mandatory internal or an external reference clock signal for generating the
timing pulse in the instrument.
Complete file path: The complete file path specifies the root directory and all subdir-
ectories that contain a file or folder.
Synonyms to this expression are "full file path" and "absolute file path".
