c. All the support units are connect to the other LISN.
d. The LISN provides 50 ohm coupling impedance for the measuring instrument.
e. The FCC states that a 50 ohm, 50 microhenry LISN should be used.
f. Both sides of AC line were checked for maximum conducted interference.
g. The frequency range from 150 kHz to 30 MHz was searched.

Mode.
i. If the emission level of the EUT in peak mode was 6 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 6 dB
margin will be retested one by one using the quasi-peak method and reported.

6. Test of Radiated Emission

Radiated emissions from 30 MHz to 1,000 MHz were measured with a bandwidth of 120 kHz according to
the methods defines in ANSI C63.4-1992. The EUT was placed on a nonmetallic stand in the open-field
site, 0.8 meter above the ground plane, as shown in section 6.3. The interface cables and equipment
positions were varied within limits of reasonable applications to determine the positions producing maximum
radiated emissions.

6.2. Test Procedures
a. The EUT was placed on a rotatable table top 0.8 meter above ground.
b. The EUT was set 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 6 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 6 dB
margin will be repeated one by one using the quasi-peak method and reported.
