The dialog displays identical measured values "Level = -33.01 dBm" and
"PEP = -22.07 dBm" for both measurements.
In the R&S SMW, when two identical baseband signals are added, they are output
at the RF output with equal average levels. The parameter "Status bar > Level = -
30 dBm" determines the level of the sum signal at the RF output; logically, the
measured level values for each of the baseband signals are 3.01 dB lower than
this sum level.
7. In the block diagram, select "Baseband B > Baseband Offsets" and enable "Base-
band B > Gain > -3 dB".
Both baseband signals are summed but the signal of "Baseband A" is 3 dB higher
than the one of the second path.
8. Open the "Baseband Powers" dialog, select "Start", and compare the measure-
ment results.
The influence of both signals on the output RF signal is different; the measured val-
ues confirm that the signal of "Baseband B" is 3 dB lower than the signal of the
