LSB: Least significant bit
LxMxN: Short form of the used system configuration, where L represents the Entity,
M the Baseband and N the Stream.
See also MxN
M
Marker: User-defined digital signal for synchronizing external devices to the generated
data stream.
Do not mistake the term marker (signal) used here with the term Marker (graphical sig-
nal display).
Marker (graphical signal display): Markers are tools for numerical readout of mea-
sured data in diagrams.
Marker signal: Marker
MIMO: Multiple Input Multiple Output
MSB: Most significant bit
multi entity: multiple entity
multiple entity: Term describing a LxMxN system configuration with Entity L > 1.
MxN: Representation of a MIMO system, where M is the number of the transmitting Tx
antennas and N the number of the receiving Rx antennas.
N
non-MIMO mode: This term is used interchangeably to the term Standard mode
NTP: A networking protocol for highly accurate clock synchronization between com-
puter systems and instruments in local area networks, or over the public internet.
P
PC: Personal computer
PN sequence: PRBS generator
Power: A term describing the signal level in the RF domain or defining the length of
the I/Q vector in the baseband domain.
PRBS generator: Delivers pseudo-random binary sequences of differing length and
duration. They are known as maximum length sequences, and are generated with the
aid of ring shift registers with feedback points determined by the polynomial.
