While working in a 4x2 or 3x2 MIMO mode that requires two two-path R&S Signal Gen-
erators, the MIMO Fading Power Correction for path A of both instruments is identical
and respectively this correction coefficient is identical for both B paths.
However, for two R&S Signal Generators connected and configured to simulate a 2x4 or
2x3 MIMO configurations, there are individual MIMO Fading Power Correction coeffi-
cients for each path and the resulting power level of each of the paths has to be calculated
separately.
Example:
SOUR:FSIM:MIMO:TAP:MATR:ROW1:COL1:RAT 0.9
SOUR:FSIM:MIMO:TAP:MATR:ROW2:COL2|3|4:RAT 1
SOUR:FSIM:MIMO:TAP:MATR:ACC
SOUR:BB:MFPC?
Response: 0.23
SOUR2:BB:MFPC?
Response: 0
The signal of path B is with 0.23 dB stronger than the signal of path A.

5.8 Baseband Signal - Baseband Block
The R&S Signal Generator provides you with the ability to generate digital modulation
signals in accordance with the definitions in the digital standards or with user-definable
characteristics. Signals are generated in realtime or from a data store with the aid of
external and internal data. You can also load externally computed modulation signals into
the R&S Signal Generator in the form of waveform files.
Several digital standards are provided, plus digital modulation with user-definable signal
characteristics, generation of waveforms with the aid of the Arbitrary Waveform Gener-
ator and generation of multi carrier CW signals with the aid of Multi Carrier CW.
The settings for digital modulation can be accessed in the block diagram via the "Base-
band" function block or with the aid of the MENU key.
The equipment layout for generating the internal, digital modulation signals includes the
options Baseband Main Module (B13) and one of the options Baseband Generator (B9/
B10/B11) .The three Baseband Generator options feature different ARB memory sizes
