Note:
1. The EUT is a ScrollToo T955 Laser with a built-in 2.4GHz transceiver.
2. Regarding to the operation frequency, the lowest, middle and highest frequency are
   selected to perform the test.
3. Lowest and highest data rates are tested in each mode. Only worst case is shown in the
   report.
4. These tests are conducted on a sample of the equipment for the purpose of demonstrating
   compliance with Part 15 Subpart C Paragraph 15.249 for spread spectrum devices.
5. The radiation measurements are performed in X, Y, Z axis positioning. Only the worst case
   is shown in the report.

2.4.   Test Procedure

       The EUT and its simulators are placed on a turn table which is 0.8 meter above ground. The
       table can rotate 360 degrees to determine the position of the maximum emission level. The
       EUT was positioned such that the distance from antenna to the EUT was 3 meters.
       The antenna is scanned between 1 meter and 4 meters to find out the maximum emission
       level. This is repeated for both horizontal and vertical polarization of the antenna. In order to
       find the maximum emission, all of the interface cables were manipulated according to ANSI
       C63.4: 2003 on radiated measurement.
       The resolution bandwidth below 1GHz setting on the field strength meter is 120 kHz and
       above 1GHz is 1MHz.
       Radiated emission measurements below 1GHz are made using broadband Bilog antenna and
       above 1GHz are made using Horn Antennas.
       The measurement is divided into the Preliminary Measurement and the Final Measurement.
       The suspected frequencies are searched for in Preliminary Measurement with the
       measurement antenna kept pointed at the source of the emission both in azimuth and
       elevation, with the polarization of the antenna oriented for maximum response. The antenna is
       pointed at an angle towards the source of the emission, and the EUT is rotated in both height
       and polarization to maximize the measured emission. The emission is kept within the
       illumination area of the 3 dB beamwidth of the antenna.
       The worst radiated emission is measured on the Final Measurement.
       The frequency range from is checked.

2.5.   Uncertainty

3.3.   Limits

       In any 100 kHz bandwidth outside the frequency band in which the spread spectrum
       intentional radiator is operating, the radio frequency power that is produced by the intentional
       radiator shall be at least 20 dB below that in the 100 kHz bandwidth within the band that
       contains the highest level of the desired power, based on either an RF conducted or a
       radiated measurement. Attenuation below the general limits specified in Section 15.209(a) is
       not required. In addition, 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)).

3.4.   Test Procedure

       The EUT and its simulators are placed on a turn table which is 0.8 meter above ground.
       The turn table can rotate 360 degrees to determine the position of the maximum emission
       level. The EUT was positioned such that the distance from antenna to the EUT was 3
       meters.
       The antenna can move up and down between 1 meter and 4 meters to find out the
       maximum emission level.
       Both horizontal and vertical polarization of the antenna are set on measurement. In order
       to find the maximum emission, all of the interface cables must be manipulated according
       to ANSI C63.4: 2003 on radiated measurement.
       The bandwidth setting below 1GHz and above 1GHz on the field strength meter is 120 kHz
       and 1MHz, respectively.



3.5.   Uncertainty

       Conducted is ± 1.27 dB
       Radiated is ± 3.9 dB
