2.3.1 Conducted Emissions

According to the requirements in Section 6.2 of ANSI C63.10: 2013, AC power-line conducted
emissions shall be measured in the frequency range between 0.15 MHz and 30MHz using
Quasi-peak and average detector modes.

2.3.2 Radiated Emissions

The EUT is placed on a turn table and the turntable shall rotate 360 degrees to determine the
position of maximum emission level. EUT is set 3m away from the receiving antenna, which varied

maximum emissions, exploratory radiated emission measurements were made according to the
requirements in Section 6.3 of ANSI C63.10: 2013

EIRP of all chains in linear terms (e.g., Watts, mW).
10. Compare the resultant electric field strength level to the applicable regulatory limit.
11. Perform radiated spurious emission test duress until all measured frequencies were complete.

Remark:
1. The other emission levels were very low against the limit.
2. The average measurement was not performed when the peak measured data under the limit of
average detection.
3. Detector AV is setting spectrum/receiver. RBW=1MHz/VBW=10Hz/Sweep time=Auto/Detector=Peak;
4. Since the out-of-band characteristics of the EUT transmit antenna will often be unknown, the use of a
conservative antenna gain value is necessary. Thus, when determining the EIRP based on the
measured conducted power, the upper bound on antenna gain for a device with a single RF output
shall be selected as the maximum in-band gain of the antenna across all operating bands, or 2 dBi,
whichever is greater. However, for devices that operate in multiple frequency bands while using the
same transmit antenna, the highest gain of the antenna within the operating band nearest in frequency
to the restricted band emission being measured may be used in lieu of the overall highest gain when
the emission is at a frequency that is within 20 percent of the nearest band edge frequency, but in no
case shall a value less than 2 dBi be used.
