The power of the output signal is displayed under
Noise Power (System Bandwidth) / Carrier + Interferer Power / Signal + Interferer
Power.

Available only for "Mode > Additive Noise".
Sets the ratio of bit energy to noise power density.
●
For "Reference Mode > Carrier", this entry determines the noise power and hence
the power of the output signal, i.e. the carrier + noise signal. It does not affect the
power of the useful signal, i.e. the carrier power is kept constant.
●
For "Reference Mode > Noise", this entry determines the power of the useful sig-
nal, i.e. the carrier power. The noise power is kept constant.
●
The power of the noise signal is derived from the selected E
the parameter "Noise Power" in the units of the useful signal.

The power of the useful signal is displayed with the parameter

Carrier Power / Signal Power
Available only for "Mode > Additive Noise" and "Mode > CW Interferer".
The name of this parameter depends on the selected output
●
For "Reference Mode > Carrier", this parameter sets the carrier power. This indica-
tion corresponds to the "Level" value in the "Status bar".
The power of the noise signal is derived from the selected C/N or S/N value and
displayed with the parameter "Noise Power" in the units of the useful signal.
●
For "Reference Mode > Noise", this parameter indicates the carrier power as
derived from the entered C/N or S/N value. This indication corresponds to the
"Level" value in the "Status bar".
The noise power can be set under "Noise Power".
Note: The peak envelope power (PEP) displayed in the "Status bar" corresponds to
the PEP value of the carrier. The parameter "Carrier+Noise (PEP)" indicates the PEP
value of the overall signal.
