•Calculating the power for the calculated bandwidth

The noise generator can be explained by the following three parameters.

Noise Bandwidth:

Sets the band for the noise to be generated.

Bandwidth set here is for the flat part of the noise as shown in the

figure below.

Calculated Bandwidth:

Normally, same as the channel bandwidth for the communication

system to be measured.

Calculated Level:

Displays the power ratio of the calculated bandwidth ( part) to

the total power of the spectrum in the figure below.

Ideal spectrum for the noise signal

The power within the calculated bandwidth is therefore figured out with

the following formula:

The power within the calculated bandwidth = RF output level (total

power) + Calculated level

… (1)
