The measurements for the Receiver Spurious
Emissions 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
temporary antenna connectors.
Testing is performed when the EUT is in
receive-only mode. The measurement is performed at the lowest and the highest channel on
which the equipment can operate. The measurements for this test are radiated and carried
out in an anechoic chamber. The test results comply with the limits shown in the
Limits on Receiver Spurious Emissions - Non-FHSS Equipment 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
radiated measurements of the Transmitter unwanted emission in the spurious domain is
described in the following steps:
- For test setup for radiated testing,
see Annex-B of EN 300 328 [3].
- Use Spectrum Analyzer as measuring
equipment.
- Switch ON the EUT and other test
equipment.
- For detailed test procedure, see
clause 5.4.10.2.1 of EN 300 328 [3] .
- 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 Rx tab and set the duration
to “infinite (0)”.
- Configure the EUT to the desired
parameters such as Channel / Frequency, Data Rate, Data Pattern, and so
forth.).
- Click on “ Start Rx Testing”.
- Carry out the tests as per Annex-C of
EN 300 328 [3] measurement procedure.
- Repeat the above for other data
rates/modulations and also other desired channels.
- The Receiver Spurious Emission levels
comply with the limits shown in the Limits on Receiver Spurious Emissions -
Non-FHSS Equipment table in CE Regulations for SRDs Operating in
License-Free 2.4 GHz/5 GHz Bands [1] for all the test cases.
