starts measuring the real level values of the digital I/Q baseband
signal.
Example:
[:SOURce<hw>]:BB:MFPCorrection?
The MIMO Fading Power Correction represents the relative power offset of the selected
path compared to the power level of the other path.
The resulting power level of the selected path is then the RF level displayed on the header
of the instrument reduced by the MIMO Fading Power Correction value.
The MIMO Fading Power Correction is necessary in case a MIMO Fading mode with
unequal steering matrix's elements is selected in the Fading block (see section "Multiple
Input Multiple Output" in the description "Fading Simulator"). Such a steering matrix is
used to simulate antennas with different power level.
While working in a 4x2 or 3x2 MIMO mode that requires two R&S Signal Generators, the
MIMO Fading Power Correction for path A of both instruments is identical and respec-
tively 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.
Return values:
float
