38 Rohde & Schwarz R&S ® SMU200A Vector Signal Generator
Extended statistic functions (R&S
®
SMU-K72 option)
At least one R&S ® SMU-B14 fading simulator must be installed. If both the R&S ® SMU-B14 and the R&S ® SMU-B15 are installed (signal
paths A and B), extended statistic functions can be used either on signal path A or B with one R&S ® SMU-K72 option. For extended
statistic functions to be used on signal paths A and B simultaneously, two R&S ® SMU-K72 must be installed.

MIMO fading (R&S
®
SMU-K74 option)
The R&S ® SMU-K74 option allows four fading channels to be simulated as is required for 1x2, 2x1 and 2x2 MIMO receiver tests.
Both the R&S ® SMU-B14 and the R&S ® SMU-B15 options must be installed (signal paths A and B) and two baseband sources
(R&S ® SMU-B9, -B10 or -B11) must be present. By combining two instruments, it is possible to simulate receiver test scenarios for 1x3,
1x4, 2x3, 2x4, 3x1, 4x1, 3x2 and 4x2 MIMO.

Steering matrix The steering matrix can be set by setting the diagonal elements of the correlation
matrix.
The correlation between corresponding fading paths of the signal paths can be set in a
correlation matrix. For each fading path index, an individual matrix can be set.
