Conducted Spurious Emissions
15.407: For transmitters operating in the 5.25-5.35 and 5.47-5.725 GHz band: all emissions outside of the
        5.25-5.35 and 5.47-5.725 GHz bands shall not exceed an EIRP of -27dBm/MHz.

        Connect the antenna port(s) to the spectrum analyzer input. Place the radio in continuous transmit mode.
        Configure the spectrum analyzer as shown below (be sure to enter all losses between the transmitter output
        and the spectrum analyzer).

                 Span:                      30 MHz-40 GHz
                 Reference Level:           20 dBm
                 Attenuation:               10 dB
                 Sweep Time:                10 s
                 Resolution Bandwidth:      1 MHz
                 Video Bandwidth:           3 MHz
                 Detector:                  Peak
                 Trace:                     Single
                 Marker:                    Peak

        Record the marker waveform peak to spur difference

Please note that scans were performed to verify that duty cycle did not have a significant impact
on the test results. Also, scans with reduced RBW and VBW settings were performed to verify that
no significant emissions were present under the noise floor.

        5.25-5.35 and 5.47-5.725 GHz bands shall not exceed an EIRP of -27dBm/MHz.

        Connect the antenna port(s) to the spectrum analyzer input. Place the radio in continuous transmit mode.
        Configure the spectrum analyzer as shown below (be sure to enter all losses between the transmitter output
        and the spectrum analyzer).

                 Span:                      30 MHz-40 GHz
                 Reference Level:           20 dBm
                 Attenuation:               10 dB
                 Sweep Time:                10 s
                 Resolution Bandwidth:      1 MHz
                 Video Bandwidth:           3 MHz
                 Detector:                  Peak
                 Trace:                     Single
                 Marker:                    Peak

        Record the marker waveform peak to spur difference

Radiated Spurious Emissions

Radiated emissions which fall in the restricted bands, as defined in Section 15.205(a), must also
comply with the radiated emission limits specified in Section 15.209(a) (see Section 15.205(c)).

        Using Vasona, configure the spectrum analyzer as shown below (be sure to enter all losses between the
        transmitter output and the spectrum analyzer). Place the radio in continuous transmit mode.

                 Span:                   1GHz – 15 GHz
                 Reference Level:        80 dBuV

         Save 2 plots:    1) Average Plot (Vertical and Horizontal), Limit= 54dBuV @3m
                          2) Peak plot (Vertical and Horizontal), Limit = 74dBuV @3m


        Place a marker at the end of the restricted band closest to the transmit frequency to show compliance.
        Also measure any emissions in the restricted bands.

This report represents the worst case data for all supported operating modes.

Please note that for the 1-18GHz test results, the noise floor is close to the limit for the Average
plots. Scans were performed with reduced RBW and VBW in order to verify that no significant
emissions were hidden by the noise floor.

Custom EMC Test Report No: EDCS -1278295




Graphical Test Results: 30MHz – 1000MHz (Transmitter on)
Note that the data displayed on the plots detailed in this appendix were measured using a 'Peak Detector'.
Please refer to the results table for the detectors used during formal measurements

Please note that the high emissions at 375MHz, 125MHz, and 625MHz are digital emissions. These will be
covered in the EMC test report. A comparison measurement was made with the radio transmitter turned off.
The emissions were still observed when the radio was off, so it can be concluded that the emissions are not
caused by the radio.
