Marker signal:
MIMO:
Multiple Input Multiple Output
MSB:

antennas and N the number of the receiving Rx antennas.
N
NTP:
(Network Time Protocol)
A networking protocol for highly accurate clock synchronization between computer sys-
tems and instruments in local area networks, or over the public internet.
P
PC:
Personal computer
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.
primary-secondary instrument mode:
Setup with two or more R&S
SMM100A or
one R&S
SMM100A and several other signal generators such as R&S SGT or R&S
SMBV that generates synchronous and time aligned signals.
The primary instrument generates and outputs a dedicated synchronization signal
(Sync Out), that has to be fed into the secondary instruments.

Remote control:
The operation of the R&S
SMM100A by remote control commands or
programs to perform automated tests. The instrument is connected to a system con-
troller via LAN/VXI-11, GPIB or USB using Virtual Instrument Software Architecture
(VISA). The instrument is controlled either directly, or supported by instrument drivers.
