7 Radiated Emissions
Test Requirement : FCC CFR47 Part 15 Section 15.209

Note:
a) The tighter limit applies at the band edges.
For example: F.S limit at 88MHz is 100uV/m
b) If measurement is made at 3m distance, then F.S Limit at 3m distance is adjusted by using the
formula of Ld1 = Ld2 * (d2/d1)2.
For example:
F.S Limit at 30m(d2) distance is 30uV/m(Ld2), then F.S Limit at 3m(d1) distance is
Ld1 = 30uV/m * (30/3)2 = 100 * 30uV/m

7.2 Test Procedure

a) Test Procedure (below 30MHz)
(1) The EUT is placed on a turntable, which is 0.8m above ground plane.
(2) The turntable shall be rotated for 360 degrees to determine the position of maximum emission
level.
(3) EUT is set 3m away from the receiving antenna.
(4) Maximum procedure was performed on the six highest emissions to ensure EUT compliance.
(5) Repeat above procedures until the measurements for all frequencies are complete.
(6) The radiation measurements are performed in X,Y,Z axes position(X denotes lying on the table,
Y denotes side stand and Z denotes vertical stand), the worst is X position.
(7) New battery used during test.
(8) A calculated substitution wire ring antenna used during test.

b) Test Procedure (above 30MHz)
(1) The EUT is placed on a turntable, which is 0.8m above ground plane.
(2) The turntable shall be rotated for 360 degrees to determine the position of maximum emission
level.
(3) EUT is set 3m away from the receiving antenna, which is moved from 1m to 4m to find out the
maximum emissions.
(4) Maximum procedure was performed on the six highest emissions to ensure EUT compliance.
(5) And also, each emission was to be maximized by changing the polarization of receiving antenna
both horizontal and vertical.
(6) Repeat above procedures until the measurements for all frequencies are complete.
(7) The radiation measurements are performed in X,Y,Z axes position(X denotes lying on the table,
Y denotes side stand and Z denotes vertical stand), the worst is X position.
(8) New battery used during test.
(9) A calculated substitution wire ring antenna used during test.

7.4 Spectrum Analyzer Setup

According to FCC Part15 Rules, the system was tested 9kHz to 1000MHz.

Below 30MHz:

Sweep Speed .....................................................Auto
IF Bandwidth ....................................................10 KHz
Video Bandwidth ..................................................10KHz
Resolution Bandwidth ..........................................10KHz

Above 30MHz:

Sweep Speed .....................................................Auto
IF Bandwidth ....................................................120 KHz
Video Bandwidth ..................................................100KHz
Quasi-Peak Adapter Bandwidth...........................120 KHz
Quasi-Peak Adapter Mode...................................Normal
Resolution Bandwidth ..........................................120kHz

7.5 Corrected Amplitude & Margin Calculation

Formula of conversion factors:the field strength at 3m was established by adding the meter reading
of the spectrum analyzer (which is set to read in units of dBuV/m) to the antenna correction factor
supplied by the antenna manufacturer. The antenna correction factors are stared in terms of dB.
The gain of the pressletor was accounted for in the spectrum analyser meter reading.
Example:
Freq(MHz) Meter Reading +ACF=FS
33 20dBuV+10.36dB=30.36dBuV/m @3m
