Note: The noise signal is not generated arbitrarily for a particular bandwidth, but
instead it is generated in steps. Noise therefore also occurs outside the set system
bandwidth. This means that the total measurable noise power (see below) usually
exceeds the value displayed here. For correct measurement of the noise power within
the system bandwidth, it is advisable to perform channel power measurement with a
signal analyzer.
Remote command:
[:SOURce<hw>]:AWGN:POWer:NOISe
Noise Power (Total Bandwidth)
Displays the power of the noise signal in the total bandwidth in "Noise Only" and "Addi-
tive Noise" mode.
Remote command:
[:SOURce<hw>]:AWGN:POWer:NOISe:TOTal?
Carrier + Noise Power / Signal + Noise Power (System Bandwidth) / Carrier +
Interferer Power / Signal + Interferer Power
Available only for "Mode > Additive Noise" and "Mode > CW Interferer".
Displays the overall power of the noise/interferer signal plus useful signal.

Additive White Gaussian Noise (AWGN) - Noise Generator
"Noise Reference Mode"
Sets the power of the interfering signal. The power of the carrier is derived from
the entered C/N or S/N value.
"Carrier Reference Mode"
Displays the power of the interfering signal. The power of the interfering signal
is derived from the entered C/N or S/N value. The carrier power is entered
under "Carrier Power".
