Appendix B:      Emission Test Results
Testing Laboratory: Cisco Systems, Inc., 170 West Tasman Drive, San Jose, CA 95134, USA

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 – 18 GHz
                 Reference Level:         80 dBuV
                 Attenuation:             10 dB
                 Sweep Time:              Coupled
                 Resolution Bandwidth:    1MHz
                 Video Bandwidth:         1 MHz for peak, 10 Hz for average
                 Detector:                Peak

        Maximize Turntable (find worst case table angle), Maximize Antenna (find worst case height)

         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 and antennas.
There are no measurable emissions above 18 GHz.
