Section 1: Overview
1.1 Test Summary

samples were assessed against the tests detailed in section 3 under the requirements of the following
specifications:


Emission                                                     Immunity

CFR47 Part 15.247                                            N/A

CFR47 Part 15.407
RSS210

The specifications listed above represent actual tests performed to demonstrate compliance against the specifications
and basic standards listed on the front cover of this report. This list is not a one to one match to the front cover for one
or more of the following reasons.
1. Basic standards call up many different test phenomena specifications such as the 61000-4-X series. The basic
    standards define which elements and levels shall be applied from these specifications and as such it is not
    appropriate to list the individual specifications on the front cover.
2. A Standard listed on the front cover may be required in a particular country but is not appropriate for the particular
    technologies included in the equipment under test. E.g. You cannot test a DC product to the mains Harmonics
    requirements in EN61000-3-2. See section 3.2.
3. Test results against a particular standard or specification may be included in a different test report. See section 3.2
    for an EDCS reference of this data.
4. Where appropriate, Cisco may have substituted a later revision of a basic standard to those referenced in the
    specification on the front sheet of this test report. This decision was based upon improved test methodology and
    repeatability and/or where the newer revision represented a more stringent test.
5. Where relevant, testing has been carried out to the requirements of both EN and IEC Specifications. This was
    possible because of the similarities of the test methods involved and the Cisco EMC test procedures.
6. Testing may have been performed to an equivalent test that satisfies the requirements of the standards and
    specifications listed on the front cover of the report. See section 3.2.
7. Where radiated emissions testing has been performed to EN55022/CISPR22 the additional requirements of VCCI:
    V- 3/2006.04, EN55022: 1994 +A1/2 and CAN/CSA- CISPR 22-02 have also been evaluated unless otherwise
    stated.
8. Testing to the requirements of CFR47 Part 15 was performed against the CISPR22 limits. The results are therefore
    deemed satisfactory evidence of compliance with Industry Canada Interference Causing Equipment Standard
    ICES-003.
9. Where assessment has been performed to CISPR24, all the applicable test requirements may have not been
    covered. Refer to the results section for the tests performed.
Notes:

1)   Where a specification listed on the front cover of this report has deviations from the basic standards listed above,
     the additional technical requirements of the specification were also assessed.
2)   Where appropriate, Cisco may have substituted a later revision of a basic standard to those referenced in the
     specification on the front sheet of this test report. This decision was based upon improved test methodology and
     repeatability and/or where the newer revision represented a more stringent test.
3)   Where relevant, testing has been carried out to the requirements of both EN and IEC Specifications. This was
     possible because of the similarities of the test methods involved and the Cisco EMC test procedures.

Section 2: Assessment Information


2.1 General
This report contains an assessment of an apparatus against Electromagnetic Compatibility Standards based upon tests
carried out on the samples submitted. The testing was performed by and for the use of Cisco systems Inc:


With regard to this assessment, the following points should be noted:


a)        The results contained in this report relate only to the items tested and were obtained in the period between the
          date of the initial assessment and the date of issue of the report. Manufactured products will not necessarily
          give identical results due to production and measurement tolerances.
b)        The apparatus was set up and exercised using the configuration and modes of operation
          defined in this report only.
c)        Where relevant, the apparatus was only assessed using the susceptibility criteria defined
           in this report and the Test Assessment Plan (TAP).
d)        All testing was performed under the following environmental conditions:
          Temperature                15°C to 35°C (54°F to 95°F)
          Atmospheric Pressure       860mbar to 1060mbar (25.4" to 31.3")
          Humidity                  10% to 75*%

          *[Where applicable] For ESD testing the humidity limits used were 30% to 60% and for EFT/B tests the
          humidity limits used were 25% to 75%.
e)        All AC testing was performed at one or more of the following supply voltages:
           110V 60 Hz (+/-20%)
           220V 50 Hz (+/-20%)

Radiated Bandedge
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.


                Reference Level:        110 dBuV
                Attenuation:            20 dB

                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.
