Example: Results calculation and interpretation at the analog I/Q Out
Enable the following settings in the " I/Q Analog > Analog I/Q Output Settings" dialog:
In the "Setup > General > Baseband Powers Simulation" dialog, enable a power mea-
surement with the following properties:
●
"Source > Baseband A"
●
"Output > I/Q Out 1"
●
"Acquisition > Nominal"
●
"I/Q level Vp (EMF) = 1.2 V"
A full scale value before the IQ modulation corresponds to 1.2 V. A -6 dBFS value for
RMS or peak would then correspond to 0.6 V.
Example: Results calculation at the RF output
The reference value for the power calculation at the RF outputs is the "Level" value, as
displayed in the status bar. A configured power offset, for example "RF > RF Level >
Offset" are considered.
Set the "RF Level = 5 dBm"
In the "Setup > Baseband Powers Simulation" dialog, enable a power measurement
with the following properties:
●
"Source > Baseband A"
●
"Output > RF A"
●
"Acquisition > Nominal"
The display shows "PEP = 15 dBm", "Level = 5 dBm"
