Operating Manual 1403.7458.32 ─ 14

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. Correct measurement of the noise power within the
system bandwidth is possible by means of channel power measurement using a signal
analyzer.

Remote command:

[:SOURce<hw>]:AWGN:POWer:NOISe

Noise Power (Total Bandwidth) - AWGN

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?

C Noise Power / Noise Power (System Bandwidth) / C
Interferer Power / Interferer Power

In "Additive Noise" and "CW Interferer" modes, displays the overall power of the noise/
interferer signal plus useful signal.

Note:

This parameter differs depending on the selected interfering and display mode,

Display Mode - AWGN

. Consequently, the overall power of the

measured signals is composed of different signals, and is also represented in different
units, dBm or dB full scale.

Tip:

In the "Additive Noise" mode, select the "Display Output Results For" (analog or

digital) before.

Remote command:

[:SOURce<hw>]:AWGN:POWer:SUM?

C Noise PEP / Noise PEP (Total Bandwidth) / C Interferer
PEP / Interferer PEP

(Additive Noise and CW Interferer)

Displays the peak envelope power of the overall signal composed of noise signal plus
useful signal.

The name of this parameter depends on the selected "Display Mode".
