Step 6:
• In case of conducted measurements on equipment with a single transmit chain, the declared antenna assembly
gain "G" in dBi shall be added to the results for each of the 1 MHz segments and compared with the limits
provided by the mask given in figures 1 or 3. If more than one antenna assembly is intended for this power
setting, the antenna with the highest gain shall be considered.
• In case of conducted measurements on smart antenna systems (equipment with multiple transmit chains), the
measurements need to be repeated for each of the active transmit chains. The declared antenna assembly gain
"G" in dBi for a single antenna shall be added to these results. If more than one antenna assembly is intended
for this power setting, the antenna with the highest gain shall be considered. Comparison with the applicable
limits shall be done using any of the options given below:
- Option 1: the results for each of the transmit chains for the corresponding 1 MHz segments shall be
added. The additional beamforming gain "Y" in dB shall be added as well and the resulting values
compared with the limits provided by the mask given in figures 1 or 3.
- Option 2: the limits provided by the mask given in figures 1 or 3 shall be reduced by 10 x log
10
(A
ch
) and
the additional beamforming gain "Y" in dB. The results for each of the transmit chains shall be
individually compared with these reduced limits.
NOTE 2: A
ch
refers to the number of active transmit chains.
It shall be recorded whether the equipment complies with the mask provided in figures 1 or 3.
5.3.9.2.2 Radiated measurement
This method shall only be used for integral antenna equipment that does not have a temporary antenna connector(s)
provided.
The test set up as described in annex B and the applicable measurement procedures described in annex C shall be used.
Alternatively a test fixture may be used.
The test procedure is as described under clause 5.3.9.2.1.
5.3.10 Transmitter unwanted emissions in the spurious domain
5.3.10.1 Test conditions
See clause 5.1 for the test conditions. These measurements shall only be performed at normal test conditions.
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. When this is
not possible, the measurement shall be performed during normal operation (hopping).
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.
The equipment shall be configured to operate under its worst case situation with respect to output power.
If the equipment can operate with different Occupied Channel Bandwidths (e.g. 20 MHz and 40 MHz), then the
equipment shall be configured to operate under its worst case situation with respect to spurious emissions.
5.3.10.2 Test method
5.3.10.2.1 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 1 or 4 or that come to within 6 dB below these limits. Each occurrence shall be recorded.
