                3.4.Operating Condition of EUT
                         3.4.1.Setup the EUT and simulator as shown as Section 3.1.

                         3.4.2.Turn on the power of all equipment.

                         3.4.3. Let the EUT work in wired modes (use USB cable connect to PC) measure it.




                3.5.Test Procedure
                       The EUT is put on the plane 0.8m high above the ground by insulating support and is
                       connected to the power mains through a line impedance stabilization network (L.I.S.N.).
                       This provides a 50ohm coupling impedance for the EUT system. Please refer the block
                       diagram of the test setup and photographs. Both sides of AC lines are checked to find out
                       the maximum conducted emission. In order to find the maximum emission levels, the
                       relative positions of equipment and all of the interface cables shall be changed according
                       to ANSI C63.4: 2003 on Conducted Emission Measurement.

                       The bandwidth of test receiver (R & S ESCS30) is set at 9kHz.

                       The frequency range from 150kHz to 30MHz is checked.

                       All the scanning waveforms are attached in Appendix I.

                4.3.Configuration of EUT on Measurement
                       The following equipment are installed on Radiated Emission Measurement to meet the
                       commission requirements and operating regulations in a manner which tends to maximize
                       its emission characteristics in normal application.

                         4.4.1.Setup the EUT and simulator as shown as Section 3.1.

                         4.4.2.Turn on the power of all equipment.

                          4.4.3. Let the EUT work in Wired modes (use USB cable connect to PC) measure it.




                4.5.Test Procedure
                       The EUT and its simulators are placed on a turntable, which is 0.8 meter high above
                       ground. The turntable can rotate 360 degrees to determine the position of the maximum
                       emission level. EUT is set 3.0 meters away from the receiving antenna, which is mounted
                       on an antenna tower. The antenna can be moved up and down between 1.0 meter and 4
                       meters to find out the maximum emission level. Broadband antenna (calibrated bilog
                       antenna) is used as receiving antenna. Both horizontal and vertical polarizations of the
                       antenna are set on measurement. In order to find the maximum emission levels, all of the
                       interface cables must be manipulated according to FCC Part 15 Subpart C on radiated
                       emission measurement.

                       The bandwidth of test receiver (R&S ESCS30) is set at 120KHz in 30-1000MHz.
                       The frequency range from 30MHz to 1000MHz is checked.

      The spectral diagrams in appendix 1 display the measurement of un-weighted peak values.
         The field strength is calculated by adding the antenna factor, high pass filter loss(if used) and cable loss, and
subtracting the amplifier gain(if any)from the measured reading. The basic equation calculation is as follows:
             Result = Reading + Corrected Factor
       Where Corrected Factor = Antenna Factor + Cable Loss + High Pass Filter Loss – Amplifier Gain

                5.5.Test Procedure
                       The EUT and its simulators are placed on a turntable, which is 0.8 meter high above
                       ground. The turntable can rotate 360 degrees to determine the position of the maximum
                       emission level. EUT is set 3.0 meters away from the receiving antenna, which is mounted
                       on an antenna tower. The antenna can be moved up and down between 1.0 meter and 4
                       meters to find out the maximum emission level. Broadband antenna (calibrated bilog
                       antenna) is used as receiving antenna. Both horizontal and vertical polarizations of the
                       antenna are set on measurement. In order to find the maximum emission levels, all of the
                       interface cables must be manipulated according to FCC Part 15 Subpart C on radiated
                       emission measurement.

                       The bandwidth of test receiver (R&S ESCS30) is set at 120KHz in 30-1000MHz.
                       The frequency range from 30MHz to 1000MHz is checked.
                        The final measurement in band 9-90kHz, 110-490kHz and above 1000MHz is performed
                        with Average detector. Except those frequency bands mention above, the final
                        measurement for frequencies below 1000MHz is performed with Quasi Peak detector.

      The spectral diagrams in appendix 1 display the measurement of un-weighted peak values.
          1. The field strength is calculated by adding the antenna factor, high pass filter loss(if used) and cable loss, and
subtracting the amplifier gain(if any)from the measured reading. The basic equation calculation is as follows:
             Result = Reading + Corrected Factor
       Where Corrected Factor = Antenna Factor + Cable Loss + High Pass Filter Loss – Amplifier Gain

          7. BAND EDGES


                7.1.The Requirement
                       7.1.1. The wanted emission within the band 26.96-27.28MHz.


                7.2.EUT Configuration on Measurement
                       The following equipment are installed on the emission Measurement to meet the
                       commission requirements and operating regulations in a manner which tends to maximize
                       its emission characteristics in normal application.
                          7.2.1.Wireless Optical Mouse (EUT)
                               Model Number        :   DS-2149-A(PM6227-2+PAN301)
                               Serial Number       :   N/A
                               Manufacturer        :   Eastern Times Technology Co., Ltd.


                7.3.Operating Condition of EUT
                          7.3.1.Setup the EUT and simulator as shown as Section 4.1.

                          7.3.2.Turn on the power of all equipment.

                          7.3.3.Let the EUT work in TX mode (On) measure it.




                7.4.Test Procedure
                       The transmitter output was fed into the spectrum analyzer and photo was taken. The
                       vertical scale is set to 10dB per division; the horizontal scale is set to 32kHz per division.
                       Star frequency are 26.96MHz, stop frequency are 27.28MHz .
                       RBW are 3kHz, VBW are 3kHz, Sweep time are 200ms.
