Step 2:

For conducted measurements on smart antenna systems using either operating mode 2 or 3 (see clause 5.1.3.2), repeat

the measurement for each of the transmit ports. For each frequency point, add up the amplitude (power) values for the

different transmit chains and use this as the new data set.

Step 3:

Add up the values for amplitude (power) for all the samples in the file.

Step 4:

Normalize the individual values for amplitude so that the sum is equal to the RF Output Power (e.i.r.p.) measured in

clause 5.3.2.

Step 5:

Starting from the first sample in the file (lowest frequency), add up the power of the following samples representing a

1 MHz segment and record the results for power and position (i.e. sample #1 to #100). This is the Power Spectral

Density (e.i.r.p.) for the first 1 MHz segment which shall be recorded.

Step 6:

Shift the start point of the samples added up in step 5 by 1 sample and repeat the procedure in step 5 (i.e. sample #2 to

#101).

Step 7:

Repeat step 6 until the end of the data set and record the radiated Power Spectral Density values for each of the 1 MHz

segments.

From all the recorded results, the highest value is the maximum Power Spectral Density for the UUT. This value, which

shall comply with the limit given in clause 4.3.2.2.2, shall be recorded in the test report.

5.3.3.2.2 Radiated measurement

This method shall only be used for integral antenna equipment which does not have a temporary antenna connector(s)

provided.

When performing radiated measurements, the UUT shall be configured and antenna(s) positioned (including smart

antenna systems and systems capable of beamforming) for maximum e.i.r.p. towards the measuring antenna.

A test site as described in annex B and applicable measurement procedures as described in annex C shall be used.

Taking into account the calibration factor from the measurement site, the test procedure is further as described under

clause 5.3.3.2.1.

5.3.4 Dwell time, Minimum Frequency Occupation and Hopping Sequence

5.3.4.1 Test conditions

See clause 5.1 for the test conditions. These measurements shall only be performed at normal test conditions.

The equipment shall be configured to operate at its maximum Dwell Time and maximum Duty Cycle.

The measurement shall be performed on a minimum of 2 hopping frequencies chosen arbitrary from the actual hopping

sequence. The results as well as the frequencies on which the test was performed shall be recorded in the test report.
