9 §2.1053 & §90.210 - Radiated Spurious Emissions
9.1 Applicable Standard
§2.1053 and §90.210

9.2 Test Procedure
TIA-603-C §2.2.12

The transmitter was placed on a wooden turntable, and it was transmitting into a non-radiating load which
was also placed on the turntable.

The measurement antenna was placed at a distance of 3 meters from the EUT. During the tests, the antenna
height and polarization as well as EUT azimuth were varied in order to identify the maximum level of
emissions from the EUT. The test was performed by placing the EUT on 3-orthogonal axis.

The frequency range up to tenth harmonic of the fundamental frequency was investigated.

Remove the EUT and replace it with substitution antenna. A signal generator was connected to the
substitution antenna by a non-radiating cable. The absolute levels of the spurious emissions were measured
by the substitution.

Spurious emissions in dB = 10 log (TX power in Watts/0.001) – the absolute level

Spurious attenuation limit in dB = 43 + 10 Log10 (power out in Watts) for EUT with a 25 KHz channel
bandwidth.

Spurious attenuation limit in dB = 50 + 10 Log10 (power out in Watts) for EUT with a 12.5 KHz channel
bandwidth.
