 4.2 Test Procedures

      5  The EUT was placed on a desk 0.8 meters height from the metal ground plane and 0.4 meter
         from the conducting wall of the shielding room and it was kept at least 0.8 meters from any
         other grounded conducting surface.
      6 Connect EUT to the power mains through a Artificial Mains Network (AMN).
      7 All the support units are connecting to the other AMN.
      8 The AMN provides 50 ohm coupling impedance for the measuring instrument.
      9 The CISPR states that a 50 ohm, 50 micro-Henry AMN should be used.
      10 Both sides of AC line were checked for maximum conducted interference.
      11 The frequency range from 150 kHz to 30 MHz was searched
      12 Set the test-receiver system to Peak Detect Function and Specified Bandwidth with Maximum
         Hold Mode.

5.2 Test Procedures
      a. The EUT was placed on a rotatable table top 0.8 meter above ground.
      b. The EUT was set 3/10 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 half wave dipole 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 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.

 5.5 Test Result and Data (30MHz ~ 1GHz)
 Position: Horizontal




REMARKS:
              1. Q.P. is abbreviation of quasi-peak individually.
              2. The emission levels of other frequencies were very low against the limit.
              3. QP Margin value = QP Limit value – QP value.
              4. Factor = Antenna Factor + Amplifier Factor + Cable loss.
              5. QP value = Factor + Reading Value.
