in electronics/electrical designs including software & firmware, PCB layout and
construction design/physical design/enclosure. The only differences between these
models are color, model number and packing configuration to be sold for marketing
purpose. Suffix (X) indicates different number of handset, Suffix (Y) indicates different
color of enclosure and different packaging material.
The circuit description is attached in the Appendix and saved with filename: descri.pdf.
2.2 Test Methodology
Both AC power line-conducted and radiated emission measurements were performed
according to the procedures in ANSI C63.4 (2003). Preliminary radiated scans and all
radiated measurements were performed in Open Area Test Sites. All Radiated tests
were performed at an antenna to EUT distance of 3 meters, unless stated otherwise in
the "Justification Section" of this Application.
2.3 Test Facility
The open area test site and conducted measurement facility used to collect the
radiated data and conducted data are at Roof Top and 2nd Floor respectively of Intertek
Testing Services Hong Kong Ltd., which is located at Garment Centre, 576 Castle
Peak Road, Kowloon, Hong Kong. This test facility and site measurement data have
been fully placed on file with the FCC.

3.0 System Test Configuration
3.1 Justification
For radiated emissions testing, the equipment under test (EUT) was setup to transmit/
receive continuously to simplify the measurement methodology. Care was taken to
ensure proper power supply voltages during testing. During testing, all cables (if any)
were manipulated to produce worst case emissions.
The EUT was powered by a 100-120VAC to 6VDC 600mA adaptor.
For the measurements, the EUT was attached to a plastic stand if necessary and
placed on the wooden turntable. If the base unit attached to peripherals, they were
connected and operational to simulate typical use. The handset was remotely located
as far from the antenna and the base as possible to ensure full power transmission
from the base. Else, the base was wired to transmit full power.
The signal was maximized through rotation and placement in the three orthogonal axes.
The antenna height and polarization were varied during the search for maximum signal
level. The antenna height was varied from 1 to 4 meters. Radiated emissions were
taken at three meters unless the signal level was too low for measurement at that
distance. If necessary, a pre-amplifier was used and/or the test was conducted at a
closer distance.
For any intentional radiator powered by AC power line, measurements of the radiated
signal level of the fundamental frequency component of the emission was performed
with the supply voltage varied between 85% and 115% of the nominal rated supply
voltage.
For transmitter radiated measurement, the spectrum analyzer resolution bandwidth
was 100 kHz for frequencies below 1000 MHz. The resolution bandwidth was 1 MHz
for frequencies above 1000 MHz.
Radiated emission measurement for transmitter was performed from the lowest radio
frequency signal generated in the device which is greater than 9 kHz to the tenth
harmonic of the highest fundamental frequency or to 40 GHz, whichever is lower.
Emission that are directly caused by digital circuits in the transmit path and transmitter
portion were measured, and the limit are according to FCC Part 15 Section 15.209.

3.1 Justification - Cont’d
Detector function for radiated emissions is in peak mode. Average readings, when
required, are taken by measuring the duty cycle of the equipment under test and
subtracting the corresponding amount in dB from the measured peak readings. A
detailed description for the calculation of the average factor can be found in section
4.2.3.
Determination of pulse desensitization was made according to Hewlett Packard
Application Note 150-2, Spectrum Analysis... Pulsed RF. The effective period (Teff)
was 625µs. With the resolution bandwidth 1MHz and spectrum analyzer IF bandwidth
3dB, the pulse desensitization factor was 0dB.
For AC line conducted emission test, the EUT along with its peripherals were placed on
a 1.0m(W)x1.5m(L) and 0.8m in height wooden table and the EUT was adjusted to
maintain a 0.4 meter space from a vertical reference plane. The EUT was connected
to power mains through a line impedance stabilization network (LISN), which provided
50ohm coupling impedance for measuring instrument. The LISN housing, measuring
instrument case, reference ground plane, and vertical ground plane were bounded
together. The excess power cable between the EUT and the LISN was bundled.
All connecting cables of EUT and peripherals were manipulated to find the maximum
emission.
All relevant operation modes have been tested, and the worst case data is included in
this report.
The DECT module was put into transmission mode when taking radiated emission data
for determining worst-case spurious emission.
3.2 EUT Exercising Software
The EUT exercise program used during radiated and conducted testing was designed
to exercise the various system components in a manner similar to a typical use.

4.0 Test Results
Data is included of the worst case configuration (the configuration which resulted in the
highest emission levels). A sample calculation, configuration photographs and data
tables of the emissions are included.
4.1 Field Strength Calculation
The field strength is calculated by adding the reading on the Spectrum Analyzer to the
factors associated with preamplifiers (if any), antennas, cables, pulse desensitization
and average factors (when specified limit is in average and measurements are made
with peak detectors). A sample calculation is included below.
FS = RA + AF + CF - AG + PD + AV
where FS = Field Strength in dBμV/m
RA = Receiver Amplitude (including preamplifier) in dBμV
CF = Cable Attenuation Factor in dB
AF = Antenna Factor in dB
AG = Amplifier Gain in dB
PD = Pulse Desensitization in dB
AV = Average Factor in -dB
In the radiated emission table which follows, the reading shown on the data table may
reflects the preamplifier gain. An example of the calculations, where the reading does
not reflect the preamplifier gain, follows:
FS = RA + AF + CF - AG + PD +AV
Example
Assume a receiver reading of 62.0 dBμV is obtained. The antenna factor of 7.4 dB and
cable factor of 1.6 dB is added. The amplifier gain of 29 dB is subtracted. The pulse
desensitization factor of the spectrum analyzer was 0 dB, and the resultant average
factor was -10 dB. The net field strength for comparison to the appropriate emission
limit is 32 dBμV/m. This value in dBμV/m was converted to its corresponding level in
μV/m.
RA = 62.0 dBμV
AF = 7.4 dB
CF = 1.6 dB
AG = 29 dB
PD = 0 dB
AV = -10 dB
FS = 62 + 7.4 +1.6 -29 +0 + (-10) = 32 dBμV/m
Level in μV/m = Common Antilogarithm [(32 dBμV/m)/20] = 39.8 μV/m

4.2.3 Transmitter Duty Cycle Calculation
Based on the Bluetooth Specification Version 2.0 / 2.1 + EDR, the transmitter ON time
for each timeslot of Bluetooth is 625µs. DH5 has the maximum duty cycle, which
consists of 5 continuous Tx slots and 1 Rx slot. Therefore one hopset take (5+1) x
625µs = 3.75ms. For one period for a pseudo-random hopping through all 79 RF
channels, it take: 79 x 3.75ms = 296.25ms.
The dwell time for DH5 is 5 x 625µs = 3.125ms.
Therefore,
Duty Cycle (DC) = Maximum On time in 100ms/100ms
= 3.125ms/100ms
= 0.03125
Average Factor (AF) of Bluetooth in dB = 20 log10 (0.03125)
= -30.1dB

4.3 Radiated Emission on the Bandedge
From the following plots, they show that the fundamental emissions are confined in the
specified band (2400MHz and 2483.5MHz). In case of emissions up to two standard
bandwidths away from the bandedge, the delta measurement technique is used for
determining bandedge compliance. Standard bandwidth is the bandwidth specified by
ANSI C63.4 (2003) for frequency being measured.
Emissions radiated outside of the specified frequency bands, except harmonics, are
attenuated by 50 dB below the level of the fundamental or to the general radiated
emission limits in FCC Part 15 Section 15.209, whichever is the lesser attenuation,
which meet the requirement of FCC Part 15 Section 15.249(d).
Radiated Emission on bandedge plots are saved with filename: be.pdf
Bandedge compliance is determined by applying marker-delta method, i.e.
Resultant Field Strength = Fundamental Emissions - Delta from the plot
Resultant field strength for the lowest and/or highest channel(s), with corresponding
average values are calculated as follows:

The resultant field strength meets the general radiated emission limit in FCC Part 15
Section 15.209, which does not exceed 74dBµV/m for peak limit and also 54dBµV/m
for average limit.
