6.1.3 Measurement Procedure and Data
      Test Procedure:      1) The mains terminal disturbance voltage test was conducted in a shielded
                              room.
                              2) The EUT was connected to AC power source through a LISN 1 (Line
                                 Impedance Stabilization Network) which provides a 50Ω/50µH + 5Ω
                                 linear
                                 impedance. The power cables of all other units of the EUT were
                                 connected to a second LISN 2, which was bonded to the ground
                                 reference plane in the same way as the LISN 1 for the unit being
                                 measured. A multiple socket outlet strip was used to connect multiple
                                 power cables to a single LISN provided the rating of the LISN was not
                                 exceeded.
                              3) The tabletop EUT was placed upon a non-metallic table 0.8m above the
                                 ground reference plane. And for floor-standing arrangement, the EUT
                                 was
                                 placed on the horizontal ground reference plane,
                              4) The test was performed with a vertical ground reference plane. The rear
                                 of the EUT shall be 0.4 m from the vertical ground reference plane. The
                                 vertical ground reference plane was bonded to the horizontal ground
                                 reference plane. The LISN 1 was placed 0.8 m from the boundary of the
                                 unit under test and bonded to a ground reference plane for LISNs
                                 mounted on top of the ground reference plane. This distance was
                                 between the closest points of the LISN 1 and the EUT. All other units of
                                 the EUT and associated equipment was at least 0.8 m from the LISN 2.
                              5) In order to find the maximum emission, the relative positions of
                                 equipment and all of the interface cables must be changed on
                                 conducted measurement.

6.2.3 Measurement Procedure and Data
     Test Procedure:   a. The EUT was placed on the top of a rotating table 0.8 meters above the
                          ground at a 3 meter semi-anechoic chamber(30MHz-1000MHz) and 3 meter
                          semi-anechoic chamber(9kHz-30MHz). The table was rotated 360 degrees
                          to determine the position of the highest radiation.
                       b. The EUT was set 10 meters(30MHz-1000MHz) and 10 meter (9kHz-30MHz)
                          away from the interference-receiving antenna, which was mounted on the
                          top of a variable-height antenna tower.
                       c.   Above 30MHz: The Analyzer/Receiver scanned from 30MHz to
                            1000MHz.The antenna height is varied from one meter to four meters above
                            the ground to determine the maximum value of the field strength. Both
                            horizontal and vertical polarizations of the antenna are set to make the
                            measurement.
                       d. Below 30MHz: The Analyzer/Receiver scanned from 9kHz to 30MHz.The
                          antenna height is 2 meters above the ground to determine the maximum
                          value of the field strength.
                       e. For each suspected emission, the EUT was arranged to its worst case and
                          then the antenna was tuned to heights from 1 meter to 4 meters (for the test
                          frequency of below 30MHz, the antenna was tuned to heights 2 meter) and
                          the rotatable table was turned from 0 degrees to 360 degrees to find the
                          maximum reading.
                       f.   The test-receiver system was set to Peak Detect Function and Specified
                            Bandwidth with Maximum Hold Mode.
                       g. If the emission level of the EUT in peak mode was 10dB lower than the limit
                          specified, then testing could be stopped and the peak values of the EUT
                          would be reported. Otherwise the emissions that did not have 10dB margin
                          would be re-tested one by one using peak, quasi-peak or average method
                          as specified and then reported in a data sheet.
                       h. Repeat above procedures until all frequencies measured was complete.
                       i.   Measurement Requirement:
                       1)This product belongs to non-ISM equipment, the field strength limit is 15uV/m
                       at 300 meter distance.
                       2)Limit: 20log(15uV/m) +20log (300/3) =23.52+40=63.52dBuV/m at 3 meters
                       distance
