and staying aimed at the emission source for
receiving the maximum signal. The final
measurement antenna elevation shall be that which
maximizes the emissions. The measurement
antenna elevation for maximum emissions shall be
restricted to a range of heights of from 1 m to 4 m
above the ground or reference ground plane.
3. Set to the maximum power setting and enable the
EUT transmit continuously.
4. Use the following spectrum analyzer settings:
(1) Span shall wide enough to fully capture the
emission being measured;
(2) Set RBW=120 kHz for f < 1 GHz, RBW=1MHz
for f>1GHz ; VBW≥RBW;
Sweep = auto; Detector function = peak; Trace
= max hold for peak
(3) For average measurement: use duty cycle
correction factor method per
15.35(c). Duty cycle = On time/100 milliseconds
On time =N1*L1+N2*L2+...+Nn-1*LNn-1+Nn*Ln
Where N1 is number of type 1 pulses, L1 is
length of type 1 pulses, etc.
Average Emission Level = Peak Emission
Level + 20*log(Duty cycle)
Corrected Reading: Antenna Factor + Cable
Loss + Read Level - Preamp Factor = Level
Test results: PASS

Note:
1. Emission Level=Peak Reading + Correction Factor; Correction Factor= Antenna Factor + Cable loss – Pre-amplifier
2. Margin (dB) = Emission Level (Peak) (dBµV/m)-Average limit (dBµV/m)
3. The emission levels of other frequencies are very lower than the limit and not show in test report.
4. Measurements were conducted from 1 GHz to the 10th harmonic of highest fundamental frequency.
5. Data of measurement shown “---“in the above table mean that the reading of emissions is attenuated more than 20 dB
below the limits or the field strength is too small to be measured.
6. Measurements were conducted in all two modulation (GFSK, Pi/4DQPSK), and the worst case Mode (Pi/4DQPSK)
was submitted only.
