"Baseband w/o
AWGN"
Activates the measurement of the interference-free baseband signal.
"Baseband with
AWGN"
Activates the measurement of the baseband signal after an AWGN noise
signal is added.
SCPI command:
[:SOURce<hw>]:BB:MEASurement:SOURce on page 688
Duration - Digital Impairments - Measurement
Enters the time for the measurement of the digital I/Q baseband signal in the range of 1
s ... 3 h. The time is to be entered in format "hh:mm:ss".
SCPI command:
[:SOURce<hw>]:BB:MEASurement:DURation on page 687
Remaining Time - Digital Impairments - Measurement
Indicates the remaining time until the measurement of the digital I/Q baseband signal is
completed. The time is displayed in format "hh:mm:ss".
SCPI command:
[:SOURce<hw>]:BB:MEASurement:RTIMe on page 688
Crest Factor - Digital Impairments - Measurement
Indicates the crest factor of the baseband signal during measurement.
SCPI command:
[:SOURce<hw>]:BB:MEASurement:CFACtor on page 687
Peak Level - Digital Impairments - Measurement
Indicates the peak level of the baseband signal relative to full scale of 0.5 V (in terms of
dB full scale) during measurement.
SCPI command:
[:SOURce<hw>]:BB:MEASurement:POWer:PEAK on page 687
Signal Level (RMS) - Digital Impairments - Measurement
Indicates the rms level of the baseband signal relative to full scale of 0.5 V (in terms of
dB full scale) during measurement.
SCPI command:
[:SOURce<hw>]:BB:MEASurement:POWer:RMS on page 687
MIMO Fading Power Correction - Digital Impairments - Measurement
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.
