mapping to the output interfaces.

BB Signals (Tx Antennas) ← System Configuration LxMxN
Defines the number of baseband signals or Tx antennas to be simulated per entity. If
one entity is enabled, the R&S SMW can generate the signal of up to 8 Tx antennas
simultaneously (see Table 3-5).
Configurations with "BB Signals (Tx Antennas) > 4" are enabled only with internal
baseband signal.
Note: Error message: "The selected configuration is not fully supported by the current
firmware".
Some baseband and fading configurations require that the R&S SMW is equipped with
hardware and software options or the selected configuration is not yet fully supported.
For more information, refer to the instrument's data sheet.

Streams (Rx Antennas) ← System Configuration LxMxN
Defines the number of streams or Rx antennas to be generated per entity. If one entity
is enabled, the R&S SMW can generate the signal of up to 8 Rx antennas simultane-
ously (see Table 3-5).
