Extended statistic functions (R&S

BTC-K1032 option)

At least one fading simulator must be installed. If two or more fading simulators are installed (signal paths A and B), extended statistic

functions can be used either on signal path A or B with one R&S

BTC-K1032 option. For extended statistic functions to be used on

signal paths A and B simultaneously, two R&S

BTC-K1032 must be installed.

MIMO fading and routing (R&S

BTC-K1034 option)

The R&S

BTC-K1034 option allows up to 2 fading channels to be simulated. Two fading simulators (R&S

BTC-B1031 and

R&S

BTC-B1032) must be installed (signal paths A and B) and two baseband sources (R&S

BTC-B1 and R&S

BTC-B2) must be

present.

Steering matrix

Can be set by setting the diagonal elements of the correlation matrix.

Correlation

Correlation between corresponding fading paths of the four signal paths can be set in a

correlation matrix. For each fading path index, an individual matrix can be set.

correlation coefficient
