4.1.3 Test Procedure
For Radiated emission below 30MHz
 a. The EUT was placed on the top of a rotating table 0.8 meters above the ground at a 3 meter chamber
     room. The table was rotated 360 degrees to determine the position of the highest radiation.

 b. The EUT was set 3 meters away from the interference-receiving antenna, which was mounted on the top
     of a variable-height antenna tower.

 c. Parallel, perpendicular, and ground-parallel orientations of the antenna are set to make the
     measurement.

 d. For each suspected emission, the EUT was arranged to its worst case and the rotatable table was turned
     from 0 degrees to 360 degrees to find the maximum reading.

 e. The test-receiver system was set to Quasi-Peak Detect Function and Specified Bandwidth with
     Maximum Hold Mode.
Note:
 1. The resolution bandwidth and video bandwidth of test receiver/spectrum analyzer is 9kHz at frequency
     below 30MHz.

For Radiated emission above 30MHz
a. The EUT was placed on the top of a rotating table 0.8 meters above the ground at 3 meter chamber room
    for test. The table was rotated 360 degrees to determine the position of the highest radiation.
b.   The EUT was set 3 meters away from the interference-receiving antenna, which was mounted on the top
     of a variable-height antenna tower.
c.   The height of antenna 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.   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 and the rotatable table was turned from 0 degrees to 360 degrees to
     find the maximum reading.
e.   The test-receiver system was set to quasi-peak detect function and specified bandwidth with maximum
     hold mode when the test frequency is below 1 GHz.


Note:
1. The resolution bandwidth and video bandwidth of test receiver/spectrum analyzer is 120kHz for
    Quasi-peak detection (QP) at frequency below 1GHz.
2.   All modes of operation were investigated and the worst-case emissions are reported.

REMARKS:
   1. Emission Level(dBuV/m) = Raw Value(dBuV) + Correction Factor(dB/m)
   2. Correction Factor(dB/m) = Antenna Factor(dB/m) + Cable Factor(dB) – Pre-Amplifier Factor(dB)
   3. Margin value = Emission Level – Limit value
   4. The emission levels were very low against the limit of frequency range 9kHz~30MHz: the amplitude of
      spurious emissions attenuated more than 20 dB below the permissible value to be report.

4.2.3    Test Procedure

a. The EUT was placed 0.4 meters from the conducting wall of the shielded room with EUT being connected
   to the power mains through a line impedance stabilization network (LISN). Other support units were
   connected to the power mains through another LISN. The two LISNs provide 50 ohm/ 50uH of coupling
   impedance for the measuring instrument.
b. Both lines of the power mains connected to the EUT were checked for maximum conducted interference.
c. The frequency range from 150kHz to 30MHz was searched. Emission levels under (Limit - 20dB) was not
   recorded.

Note: All modes of operation were investigated and the worst-case emissions are reported.
