  6. Test of Spurious Emission (Radiated)
    6.1 Test Limit
         In any 100kHz bandwidth outside the frequency band in which the spread spectrum or
         digitally modulated intentional radiator is operating, the radio frequency power that is
         produced by the intentional radiator shall be at least 20dB below that in the 100kHz
         bandwidth within the band that contains the highest level of the desired power, based on
         either an RF conducted or a radiated measurement. If the transmitter measurement is
         based on the maximum conducted output power, the attenuation required under this
         paragraph shall be 30dB instead of 20dB. In addition, radiated emissions which fall in
         section 15.205(a) the restricted bands must also comply with the radiated emission limit
         specified in section 15.209(a).

    6.2 Test Procedures
         a. The EUT was placed on a rotatable table top 0.8 meter above ground.
         b. The EUT was set 3 meters from the interference receiving antenna which was mounted on
            the top of a variable height antenna tower.
         c. The table was rotated 360 degrees to determine the position of the highest radiation.
         d. The antenna is a broadband antenna and its height is varied between one meter and four
            meters above ground to find the maximum value of the field strength both horizontal
            polarization and vertical polarization of the antenna are set to make the measurement.
         e. For each suspected emission the EUT was arranged to its worst case and then tune the
            antenna tower (from 1 M to 4 M) and turn table (from 0 degree to 360 degrees) to find the
            maximum reading.
         f. Set the test-receiver system to Peak or CISPR quasi-peak Detect Function and specified
             bandwidth with Maximum Hold Mode.
         g. If the emission level of the EUT in peak mode was 3 dB lower than the limit specified, then
             testing will be stopped and peak values of EUT will be reported, otherwise, the emissions
             which do not have 3 dB margin will be repeated one by one using the quasi-peak method
             and reported.
         h. For testing above 1GHz, the emission level of the EUT in peak mode was 20dB lower than
            average limit (that means the emission level in peak mode also complies with the limit in
            average mode), then testing will be stopped and peak values of EUT will be reported,
            otherwise, the emissions will be measured in average mode again and reported.
         i. “Cone of radiation” has been considered to be 3dB bandwidth of the measurement
             antenna.

  7. Test of Spurious Emission (Conducted)

    7.1 Test Limit

         Below –20dB of the highest emission level of operating band (In 100 kHz Resolution Bandwidth)

    7.2 Test Procedure

         a. The transmitter output was connected to the spectrum analyzer via a low loss cable.
         b. Set RBW of spectrum analyzer to 100 KHz and VBW of spectrum analyzer to 300 KHz
            with convenient frequency span including 100 KHz bandwidth from band edge.
         c. Peak conducted output power measured within any 100 kHz outside the authorized
            frequency band shall be attenuated by at least 20dB relative to the maximum measured
            in-band peak PSD level.
         d. The band edges was measured and recorded.

  10. Maximum Peak and Average Output Power
    10.1 Test Limit

         The Maximum Peak Output Power Measurement is 30dBm.


    10.2 Test Procedures

         The antenna port (RF output) of the EUT was connected to the input (RF input) of a power
         meter. Power was read directly from the meter and cable loss connection was added to the
         reading to obtain power at the EUT antenna terminal. The EUT Output Power was set to
         maximum to produce the worse case test result.
