Noise Power (Total Bandwidth)
Displays the power of the noise signal in the total bandwidth in "Noise Only" and "Addi-
tive Noise" mode.
See also Figure 4-3.
Remote command:
[:SOURce<hw>]:AWGN:POWer:NOISe:TOTal? on page 801
Carrier + Noise Power, Signal + Noise Power (System Bandwidth), Carrier + Inter-
ferer Power, Signal + Interferer Power
In "Additive Noise" and "CW Interferer" mode, displays the overall power of the noise/
interferer signal plus useful signal.
The output selected with the parameter Show Powers for Output determines:
●
The name of this parameter
●
The units the overall power is measured in, dBm or dB (full scale)
See also Figure 4-3.
Remote command:
[:SOURce<hw>]:AWGN:POWer:SUM? on page 801
Carrier + Noise PEP, Signal + Noise PEP (Total Bandwidth), Carrier + Interferer
PEP, Signal + Interferer PEP
In "Additive Noise" and "CW Interferer" mode, displays the peak envelope power (PEP)
of the overall signal comprised of noise signal plus useful signal.
The output selected with the parameter Show Powers for Output determines:
●
The name of this parameter
●
The units the overall power is measured in, dBm or dB (full scale)
Note: The peak envelope power ("PEP") displayed in the "Status bar" corresponds to
the PEP value of the carrier.
Remote command:
[:SOURce<hw>]:AWGN:POWer:SUM:PEP? on page 802
Noise Bandwidth
For "Additive Noise" and "Noise Only" modes and with activated AWGN generator,
indicates the real noise bandwidth.
See also Figure 4-2.
Remote command:
[:SOURce<hw>]:AWGN:BWIDth:NOISe? on page 799
Resulting CW Frequency Offset
In "CW Interferer" mode, indicates the resulting frequency offset of the sine wave.
