4.1.3 TEST PROCEDURES
a. The EUT was placed on the top of a rotating table 0.8 meters (for below 1GHz) / 1.5 meters (for
above 1GHz) 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. Height of receiving 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 Peak Detect Function and Specified Bandwidth with Maximum
Hold Mode.
f. If the emission level of the EUT in peak mode was lower than the limit specified, then testing could
be stopped and the peak values of the EUT would be reported. Otherwise the emissions would be
re-tested one by one using peak, quasi-peak or average method as specified and then reported in a
data sheet.
NOTE:
1. The resolution bandwidth and video bandwidth of test receiver/spectrum analyzer is 120kHz for
Quasi-peak detection at frequency below 1GHz.
2. The resolution bandwidth of test receiver/spectrum analyzer is 1MHz and video bandwidth is 3MHz
for Peak detection at frequency above 1GHz.
3. The resolution bandwidth of test receiver/spectrum analyzer is 1MHz and the video bandwidth is
10Hz for Average detection (AV) at frequency above 1GHz.
4. All modes of operation were investigated and the worst-case emissions are reported.

4.2.3 TEST PROCEDURES
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.

Remarks:
1. Q.P. and AV. are abbreviations of quasi-peak and average individually.
2. The emission levels of other frequencies were very low against the limit.
3. Margin value = Emission level – Limit value
4. Correction factor = Insertion loss + Cable loss
5. Emission Level = Correction Factor + Reading Value

TEST PROCEDURE
1.
Set resolution bandwidth (RBW) = approximately 1% of the emission bandwidth
2.
Set the video bandwidth (VBW) ≥ 3 x RBW, Detector = Peak.
3.
Trace mode = max hold.
4.
Sweep = auto couple.
5.
Measure the maximum width of the emission that is constrained by the frequencies associated
with the two amplitude points (upper and lower) that are attenuated by 6 dB relative to the
maximum level measured in the fundamental emission.
