4. Operation and Monitoring of the EUT during Testing
4.1. Operating Modes
The EUT was tested in the following operating mode(s):
• All 802.11b and 802.11g modes were initially tested in order to establish which operating modes
produced the highest EIRP and highest emission levels. 802.11b 11 Mbps and 802.11g 24 Mbps
modes were found to be worst case modes. Final measurements were performed in these modes.
• Transmitting on bottom, middle and top channels.

4.2. Configuration and Peripherals
The EUT was tested in the following configuration(s):
• NMO5E2400B Pulse Wi-Fi Antenna was used during testing.
• Power was supplied from a bench power supply.
• All cabling present on the wiring harness was correctly terminated when not in use.
• Manufacturing Mode of the software was enabled to allow control of Wi-Fi settings. This was enabled
and controlled via the serial port of the wiring harness connected to a PC equipped with any generic
terminal software. It enabled manual setup of the EUT Wi-Fi channel, data rate and power for test
purposes.

5. Measurements, Examinations and Derived Results
5.1. General Comments
Measurement uncertainties are evaluated in accordance with current best practice. Our reported expanded
uncertainties are based on standard uncertainties, which are multiplied by an appropriate coverage factor to
provide a statistical confidence level of approximately 95%. Please refer to Section 6 Measurement
Uncertainty for details.

referencing ANSI C63.4 (see note below)

Note(s):

1. Tests were performed using a combination of the conducted test method described in ANSI C63.10
Section 6.10.2 and the test methods for radiated emissions measurements described in Sections 6.3 and
6.6. The reason for this being that the measurements were performed radiated as the EUT has an
external antenna and the Customer requested that all measurements were performed with the antenna
connected.
2. EIRP was measured using the channel power function of a spectrum analyser. Measurement
bandwidths were set automatically by the spectrum analyser.

FCC Part: 15.247(d) & 15.209(a)
Test Method Used: As detailed in ANSI C63.10 Sections 6.3 and 6.5

Note(s):

1. The final measured value, for the given emission, in the table above incorporates the calibrated antenna
factor and cable loss
2. The preliminary scans showed similar emission levels below 1 GHz, for each channel of operation.
Therefore final radiated emissions measurements were performed with the EUT set to the top channel
only.
3. All other emissions were at least 20 dB below the appropriate limit or below the noise floor of the
measurement system.
4. Transmitter spurious emissions were performed with the EUT transmitting with a data rate of 24 Mbps,
as this was seen to have the highest power level and therefore deemed to be worst case

6. Measurement Uncertainty
No measurement or test can ever be perfect and the imperfections give rise to error of measurement in the
results. Consequently the result of a measurement is only an approximation to the value of the measurand
(the specific quantity subject to measurement) and is only complete when accompanied by a statement of
the uncertainty of the approximation.
The expression of uncertainty of a measurement result allows realistic comparison of results with reference
values and limits given in specifications and standards.
The uncertainty of the result may need to be taken into account when interpreting the measurement results.
The reported expanded uncertainties below are based on a standard uncertainty multiplied by an appropriate
coverage factor such that a confidence level of approximately 95% is maintained. For the purposes of this
document “approximately” is interpreted as meaning “effectively” or “for most practical purposes”.

Confidence Calculated
Measurement Type Range
Level (%) Uncertainty
Radiated Maximum Peak Output Power 2.4 GHz to 2.4835 GHz 95% ±2.94 dB
Radiated Spurious Emissions 30 MHz to 26.5 GHz 95% ±2.94 dB

The methods used to calculate the above uncertainties are in line with those recommended within the
various measurement specifications. Where measurement specifications do not include guidelines for the
evaluation of measurement uncertainty the published guidance of the appropriate accreditation body is
followed.
