• Sweep Points: 9 970
• Sweep time: Auto
Allow the trace to stabilize. Any emissions identified during the sweeps above and that fall within the 6 dB range below
the applicable limit or above, shall be individually measured using the procedure in clause 5.3.11.2.1.2 and compared to
the limits given in tables 2 or 5.
Step 3:
The emissions over the range 1 GHz to 12,75 GHz shall be identified.
Spectrum analyser settings:
• Resolution bandwidth: 1 MHz
• Video bandwidth: 3 MHz
• Detector mode: Peak
• Trace Mode: Max Hold
• Sweep Points:
11 750
• Sweep time: Auto
Allow the trace to stabilize. Any emissions identified during the sweeps above that fall within the 6 dB range below the
applicable limit or above, shall be individually measured using the procedure in clause 5.3.11.2.1.2 and compared to the
limits given in tables 2 or 5.
Frequency Hopping equipment may generate a block (or several blocks) of spurious emissions anywhere within the
spurious domain. If this is the case, only the highest peak of each block of emissions shall be measured using the
procedure in clause 5.3.11.2.1.2.
Step 4:
• In case of conducted measurements on smart antenna systems (equipment with multiple receive chains), the
steps 2 and 3 need to be repeated for each of the active receive chains (A
ch
).
• The limits used to identify emissions during this pre-scan need to be reduced with 10 × log
10
(A
ch
) (number of
active receive chains).
5.3.11.2.1.2 Measurement of the emissions identified during the pre-scan
The steps below shall be used to accurately measure the individual unwanted emissions identified during the pre-scan
measurements above.
Step 1:
The level of the emissions shall be measured using the following spectrum analyser settings:
• Centre Frequency: Frequency of emission identified during the pre-scan
• Resolution Bandwidth: 100 kHz (< 1 GHz) / 1 MHz (> 1 GHz)
• Video Bandwidth: 300 kHz (< 1 GHz) / 3 MHz (> 1 GHz)
• Frequency Span: Wide enough to capture each individual emission indentified during the pre-scan
• Sweep mode: Continuous
• Sweep time: Auto
• Trigger: Free run
• Detector: RMS
