Fig. 4-2 Channel Power Measurement of FM Signal

Occupied bandwidth measurement

Taking the measurement of the occupied bandwidth of the FM signal for example, this section describes how to use
the occupied bandwidth measurement function of S3302 series spectrum analyzer to measure the occupied
bandwidth of the signal.

1) Definition of occupied bandwidth

The occupied bandwidth refer to the bandwidth including energy of certain proportion to the total transmitted power,
with the center frequency of the specified channel as the center. By using the occupied bandwidth measurement
function of S3302 series spectrum analyzer, measurement results can be given rapidly, clearly and accurately.
Depending on the modulation mode, two methods can be applied to calculate the occupied bandwidth.

a) Power percentage:

The occupied bandwidth of the signal is obtained by calculating the bandwidth of the frequency of certain
percentage to the total power of the transmitted power. The power percentage can be set by the user.

b) Power drop XdB:
