    8.4   Test Result of the Bandedge


          If any 100 kHz bandwidth outside these frequency bands, the radio frequency power that is
    produced by the modulation products of the spreading sequence, the information sequence and the
    carrier frequency shall be either at least 20 dB below that in any 100 kHz bandwidth within the
    band that contains the highest level of the desired power or shall not exceed the general levels
    specified id §15.209(a),


          We perform this section by the conducted manner, the RBW is set to 1MHz and VBW=RBW.
    We’d made the observation up to 10th harmonics and the criterion is all the harmonic/spurious
    emissions must be 20dB below the highest emission level measured. If the emissions fall in the
    restric ted bands stated in the Part15.205(a) must also comply with the radiated emission limits
    specified in Part15.209(a). (Peak mode: RBW=VBW=1MHz. Average mode: RBW=1MHz,
    VBW=10Hz)


          The following pages show our observations referring to the channel 1 and 11 respectively.


          Test Condition & Setup: same as < 3.1 >

    This is the hard copy of our bandedge measurement generated by our bandedge testing program.
The pictures shown above is the bandedge of channel 1 and 11.
    1. The lob right and left by the fundamental side is already 20dB below the highest emission level.
    2. The emissions recorded in the restricted band is do comply with the Part 15.209(a) – as below.
