The measurements for Transmitter unwanted
emission outside the 5 GHz RLAN bands are performed at normal environmental conditions
only. The level of spurious emissions are measured as, either:
- Their power in a specified load
(conducted spurious emissions) and their effective radiated power when radiated by
the cabinet or structure of the equipment (cabinet radiation); or
- Their effective radiated power when
radiated by cabinet and antenna in case of integral antenna equipment with no
antenna connectors.
The EUT is configured to operate under its
worst case situation with respect to unwanted emissions outside the 5 GHz RLAN bands and
is tested on those channels and channel bandwidths specified in table 6. The test
results comply with the limits shown in the Limits on Transmitter Unwanted Emissions
- Outside the 5 GHz RLAN Bands table in CE Regulations for SRDs Operating in
License-Free 2.4 GHz/5 GHz Bands [1] and are recorded in the test report. The test procedure for
Transmitter unwanted emissions outside the 5 GHz RLAN bands measurement is described in
the following steps:
- For test setup for radiated testing,
see Annex-B of of EN 301 893 [4].
- Use Spectrum Analyzer as test
equipment.
- For detailed test procedures, see
clause 5.4.5.2.1 of EN 301 893 [4].
- Switch ON the EUT and other test
equipment.
- Set the Spectrum Analyzer to the
settings specified in clause 5.4.5.2.1 of EN 301 893 [4] .
- Use the Radio Testing Tool [9] to setup and configure the EUT. For setting and up configuring
the EUT, see the Radio Testing Tool User's Guide [10].
- Open the Radio Testing Tool [9] and setup the link with the EUT by using the Setup tab.
- Open the Tx tab and set the
transmission mode to “Continuous”.
- Configure the EUT to the desired
parameters such as Channel/Frequency, Data Rate, Data Pattern, Power Level, and so
forth).
- Click on “ Start Tx Testing”.
- Measure the unwanted emission levels
as per the procedure described in the clause 5.4.5.2.1 of EN 301 893 [4].
- Repeat the above for other data
rates/modulations and also other desired channels.
- The Unwanted Emission levels outside
the 5 GHz RLAN bands domain comply with the limits shown in the Limits on
Transmitter Unwanted Emissions - Outside the 5 GHz RLAN Bands table in
CE Regulations for SRDs Operating in License-Free 2.4 GHz/5 GHz
Bands [1] for all the test cases.
