Trace Mode: Max Hold
Step 2:
Wait until the trace is completed.
Find the peak value of the trace and place the analyser marker on this peak.
Step 3:
Use the 99 % bandwidth function of the spectrum analyser to measure the Occupied Channel Bandwidth of the UUT.
This value shall be recorded.
NOTE: Make sure that the power envelope is sufficiently above the noise floor of the analyser to avoid the noise
signals left and right from the power envelope being taken into account by this measurement.
5.3.8.2.2 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 5.3.8.2.1.
5.3.9 Transmitter unwanted emissions in the out-of-band domain
5.3.9.1 Test conditions
See clause 5.1 for the test conditions. These measurements have to be performed at normal environmental conditions
and shall be repeated at the extremes of the operating temperature range.
In the case of equipment intended for use with an integral antenna and where no external (temporary) antenna
connectors are provided, a test fixture as described in clause B.3 may be used to perform relative measurements at the
extremes of the operating temperature range.
For systems using FHSS modulation, the measurements 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), than each
channel bandwidth shall be tested separately.
5.3.9.2 Test method
5.3.9.2.1 Conducted measurement
The applicable mask is defined by the measurement results from the tests performed under clause 5.3.8 (Occupied
Channel Bandwidth).
The Out-of-band emissions within the different horizontal segments of the mask provided in figures 1 and 3 shall be
measured using the steps below. This method assumes the spectrum analyser is equipped with the Time Domain Power
option.
