For a given operating frequency, the width of the power envelope is (f

－ f

. In equipment that

allows adjustment or selection of difference operation frequencies, the power envelope takes up

difference positions in the allowed band. The frequency range is determined by the lowest value of f

and the highest value of f

resulting from the adjustment of the equipment to the lowest and highest

operating frequencies.

For all equipment the frequency range shall lie within the band 2.4GHz to 2.4835GHz (f

> 2.4GHz

and f

< 2.4835GHz).

4.5. Test Procedure

The measurement procedure shall be as follows:

a) Place the spectrum analyzer in video averaging mode with a minimum of 50 sweeps selected and

activate the transmitter with modulation applied. The RF emission of the equipment shall be

displayed on the spectrum analyzer;

b) Select lowest operating frequency of the equipment under test;

c) Using the marker of the spectrum analyzer, find lowest frequency below the operating frequency at

which spectral power density drops below the level given in limit (subclause 5.2.3);

d) Select the highest operating frequency of the equipment under test;

e) Find the highest frequency at which the spectral power density drops below the value given in limit

(subclause 5.2.3.);

f) The difference between the frequencies measured in steps c) and e) is the frequency range.

4.6. Uncertainty

The measurement uncertainty is defined as ± 100 kHz

4.7. Test Specification

According to ETSI EN 300 328:V1.4.1 (2003-04)

4.8. Test Result

The emission from the EUT was below the specified limits. The worst-case emissions are shown in

section 8. The acceptance criterion was met and the EUT passed the test.
