The measurements for Receiver Spurious
emissions is 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 are configured to operate into a
continuous receive mode and is tested on those channels and channel bandwidths specified
in the Limits on Nominal and Occupied Channel Bandwidth table in CE
Regulations for SRDs Operating in License-Free 2.4 GHz/5 GHz Bands
[1]. 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 table of 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 Receiver spurious emissions 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 measuring
equipment.
- Switch ON the EUT and other test
equipment.
- For detailed test procedure, see
clause 5.4.7.2.1 of EN 301 893 [4].
- Use the Radio Testing Tool [9] to setup and configure the EUT. Ffor 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 301 893 [4] 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
table of CE Regulations for SRDs Operating in License-Free 2.4 GHz/5
GHz Bands [1] for all the test cases.
