A.5 Radiated Spurious Emission
A.5.1 Reference
FCC CFR 47 Part 2, Clause 2.1053
FCC CFR 47 Part 27, Clause 27.53 (m)

A.5.2 Method of measurement
The measurements procedures in TIA-603-E: 2016 are used. This measurement is carried out in
semi-anechoic chamber.
A preliminary profile of the Spurious Radiated Emissions was obtained by operating the EUT on a
remotely controlled turntable within the chamber. Measurements of emissions from the EUT were
obtained with the measurement antenna in both horizontal and vertical polarisations.
Emissions identified within the range 30MHz to 40GHz were then formally measured using a peak
detector as the worst case.
The limits for outside a licensee’s frequency band(s) of operation the power of the spurious
emissions have been calculated, as shown below using the following formula:
     Field Strength of Carrier - (43 + 10Log (P)) dB
Where:
     Field Strength is measured in dBμV/m
     P is measured Transmitter Power in Watts
The EUT was measured with the antenna height varied between 1 and 4 m with the turntable
rotated between 0 and 360 degrees. The emission of any outside a licensee’s frequencies within
20dB of the limit were measured with the substitution method used according to the standard.
The measurements were performed at a 3m distance unless otherwise stated.

A.5.3 Measurement limit
The field strength of the carrier has been calculated assuming that the power is to be fed to a
half-wave tuned dipoles as per 2.1053 (a).
     E(v/m)=(30 x Gi x Po )0.5 / d
Where
     Gi is the antenna gain of ideal half-wave dipoles,
     Po is the power out of the transceiver in W,
     d is the measurement distance in meter.
Therefore at 3m measurement distance the field strength using the lowest transceiver output
power would be:
E(v/m)=(30 x 1.64 x 16.56)0.5 / 3 = 9.51V/m = 139.57 dBμV/m
As per 24.238 (a) the spurious emission must be attenuated by 43 + 10log (Po) dB this gives:
43 + 10log(16.56) = 55.19 dB
Therefore the limit at 3m measurement distance is:
139.57 – 55.19 = 84.4 dBμV/m
These limits have been used to determine Pass or Fail for the harmonics measured and detailed in
the following results.
