"1", "2"
Option: R&S SMW-K821
An 1x8x8 MIMO configuration requires two R&S SMW, where each of
the instruments generates a subset of 32 fading channels, out of the
total 64 channels.
This parameter defines which fading channels from the MIMO matrix
are calculated by the selected instrument. The "Subset" selected in
each of the two connected instrument has to be different.
See also Chapter 4.9.8, "How to Generate a 8x8 MIMO Signal with
Two R&S SMW", on page 206.
"All"
Option: R&S SMW-B15/-K75
An 1x8x8 MIMO configuration is generated with a single R&S SMW.
Remote command:
:SCONfiguration:MIMO:SUBSet on page 917
BB Bandwidth
Option: R&S SMW-B15/-K822/-K823
Sets the baseband signal bandwidth, that is supported by the fading simulator.
The value range and the maximal available bandwidth depend on the installed options
and the selected MIMO configuration.
For example:
●
In MIMO configurations with fewer than 8 channels, the max. baseband bandwidth
is 400 MHz.
●
In MIMO configurations with fewer than 4 channels, the max. baseband bandwidth
is 800 MHz.
For more information, see data sheet.
Remote command:
:SCONfiguration:BBBW on page 917
CA Bandwidth
Option: R&S SMW-B15/-K822/-K823
Indicates the resulting channel aggregation aggregation (CA) bandwidth, claculated
based on the MIMO configurtion and the "BB Bandwidth".
The "CA Bandwidth" represents the signal bandwidth at the stream mapper.
For more information, see data sheet.
Remote command:
:SCONfiguration:CABW? on page 918
Baseband Source Config
Determines whether coupled or separated baseband sources are used (see "Coupled
or separate baseband sources" on page 112).
Note: The RF outputs are disabled, if you apply new System Configuration LxMxN
and/or change the Baseband Source Config.
