5.3.10.2.2 Radiated measurement

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

The test procedure is further as described under clause 5.3.10.2.1.

5.3.11 Receiver spurious emissions

5.3.11.1 Test conditions

See clause 5.3 for the test conditions. These measurements shall only be performed at normal test conditions.

The level of spurious emissions shall be measured as, either:

a) 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

b) their effective radiated power when radiated by cabinet and antenna.

Testing shall be performed when the equipment is in a receive-only mode.

For systems using wide band modulations other than FHSS, the measurement shall be performed at the lowest and the

highest channel on which the equipment can operate. These frequencies shall be recorded.

For systems using FHSS modulation, the measurements may be performed when normal hopping is disabled. In this

case measurements need to be performed when operating at the lowest and the highest hopping frequency. These

frequencies shall be recorded. When disabling the normal hopping is not possible, the measurement shall be performed

during normal operation (hopping).

5.3.11.2 Test method

5.3.11.2.1 Conducted measurement

In case of conducted measurements, the radio equipment shall be connected to the measuring equipment via a suitable

attenuator.

The spectrum in the spurious domain (see figures 1 or 3) shall be searched for emissions that exceed the limit values

given in tables 2 or 5 or that come to within 6 dB below these limits. Each occurrence shall be recorded.

The measurement procedure shall be as follows.

5.3.11.2.1.1 Pre-scan

The test procedure below shall be used to identify potential unwanted emissions of the UUT.

Step 1:

The sensitivity of the spectrum analyser should be such that the noise floor is at least 12 dB below the limits given in

tables 2 or 5.

Step 2:

The emissions over the range 30 MHz to 1 000 MHz shall be identified.

Spectrum analyser settings:

• Resolution bandwidth: 100 kHz

• Video bandwidth: 300 kHz

• Detector mode: Peak

• Trace Mode: Max Hold
