F
Fading channel: In a 2x2 MIMO fading configuration, there are four fading channels
between the transmit (Tx) and the receive (Rx) antennas. In this description, each fad-
ing channel is represent as a block with name following the naming convention
"F
<Tx><Rx>
", where Tx and Rx are the antennas (e.g. A and B in a 2x2 MIMO configura-
tion)
Do not mistake the terms fading channel and Fading path.
Fading path: Each Fading channel consists of several fading paths. The number of
the paths depends on the fading configuration.
File transfer: The transmission of files from or to the instrument by a remote client.
The instrument supports the standard methods File Transfer Protocol (FTP) and file
sharing according to Server Message Protocol (SAMBA/SMB).
Full file path: Complete file path

Level: In the Baseband domain, a term describing the signal level of the independent I
and Q signals during signal processing (e.g. baseband signal leveling, modulation,
etc.).
LSB: Least significant bit
LxMxN: Short form of the used system configuration, where L represents the Entity,
M the Baseband and N the Stream.
