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".
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 usually exceeds the
value displayed here. For correct measurement of the noise power within the system
bandwidth, we recommend that you measure the channel power with a signal analyzer.
See also Figure 5-3.

Noise Power (Total Bandwidth)
Displays the power of the noise signal in the total bandwidth in "Noise Only" and "Addi-
tive Noise" mode.
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 usually exceeds the
value displayed here. For correct measurement of the noise power within the system
bandwidth, we recommend that you measure the channel power with a signal analyzer.
