  7. Test of Conducted Spurious Emission

     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.

  9. 6dB Bandwidth Measurement Data

     9.1 Test Limit
           The minimum of 6dB Bandwidth Measurement is 0.5 MHz.

     9.2 Test Procedures
           a. The transmitter output was connected to the spectrum analyzer.
           b. Set RBW of spectrum analyzer to 1~5% of the emission bandwidth and VBW ≥ 3x RBW.
           c. The 6 dB bandwidth is defined as the total spectrum the power of which is higher than peak
              power minus 6 dB.
           d. The 6dB Bandwidth was measured and recorded.

  10. Maximum Peak and Average Output Power
     10.1 Test Limit
           The Maximum Peak Output Power Measurement is 30dBm.
           If transmitting antennas of directional gain greater than 6 dBi are used, the peak output power
           shall be reduced by the amount in dB that the directional gain of the antenna exceeds 6 dBi

     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.

  11. Power Spectral Density
     11.1 Test Limit
           The Maximum of Power Spectral Density Measurement is 8dBm.
           If transmitting antennas of directional gain greater than 6 dBi are used, the power spectral density
           shall be reduced by the amount in dB that the directional gain of the antenna exceeds 6 dBi

     11.2 Test Procedures
           a. The transmitter output was connected to spectrum analyzer.
           b. The spectrum analyzer’s resolution bandwidth were set at 3kHz RBW and 30KHz
                 VBW as that of the fundamental frequency. Set the sweep time=auto couple.
           c.    The power spectral density was measured and recorded.
