The EUT is configured for testing as depicted in Figure 2.

3.1.2 Modes of Operation
The EUT is capable of operating as a Bluetooth transceiver and as a broadcast (AM/FM) receiver. As a Bluetooth
2.0+EDR device, the EUT is capable of operation as a transceiver employing GFSK, pi/4-DPSK, and 8DPSK
modulations at 1, 2, and 3 Mbps data rates. Test samples were placed into worst-case operating modes using an
Agilent N4010A Bluetooth test set. Please note that the different operating modes (data-mode, acquisition-mode) of
a Bluetooth device do not influence the channel spacing or peak output power. There is only one transmitter which
is driven by identical input parameters concerning these values.

4 Emissions
4.1 General Test Procedures
4.1.1 Radiated Test Setup and Procedures
Radiated electromagnetic emissions from the EUT are first pre-scanned in our screen room. Spectrum and modulation
characteristics of all emissions are recorded. Instrumentation, including spectrum analyzers and other test equipment
as detailed in Section 1.8 are employed. After pre-scan, emission measurements are made on the test site of record.
If the EUT connects to auxiliary equipment and is table or floor standing, the configurations prescribed in relevant
test standards are followed. Alternatively, a layout closest to normal use (as declared by the provider) is employed
if the resulting emissions appear to be worst-case in such a configuration. See Figure 3. All intentionally radiating
elements that are not fixed-mounted in use are placed on the test table lying flat, on their side, and on their end
(3-axes) and the resulting worst case emissions are recorded. If the EUT is fixed-mounted in use, measurements are
made with the device oriented in the manner consistent with installation and then emissions are recorded. If the
EUT exhibits spurious emissions due to internal receiver circuitry, such emissions are measured with an appropriate
carrier signal applied.

Radiated Emissions Table

Figure 3: Radiated Emissions Diagram of the EUT.

For devices with intentional emissions below 30 MHz, a shielded loop antenna and/or E-field and H-Field broad-
band probes are used depending on the regulations. Shielded loops are placed at a 1 meter receive height at the desired
measurement distance. For exposure in this band, the broadband probes employed are 10cm diameter single-axis
shielded transducers and measurements are repeated and summed over three axes.
Emissions between 30 MHz and 1 GHz are measured using calibrated broadband antennas. For both horizontal
and vertical polarizations, the test antenna is raised and lowered from 1 to 4 m in height until a maximum emission
level is detected. The EUT is then rotated through 360o in azimuth until the highest emission is detected. The test
antenna is then raised and lowered one last time from 1 to 4 m and the worst case value is recorded. Emissions
above 1 GHz are characterized using standard gain or broadband ridge-horn antennas on our OATS with a 4 × 5
m rectangle of ECCOSORB absorber covering the OATS ground screen and a 1.5m table height. Care is taken to
ensure that test receiver resolution and video bandwidths meet the regulatory requirements, and that the emission
bandwidth of the EUT is not reduced. Photographs of the test setup employed are depicted in Figure 4.
Where regulations allow for direct measurement of field strength, power values (dBm) measured on the test
receiver / analyzer are converted to dBµV/m at the regulatory distance, using

Edist = 107 + PR + KA − KG + KE − CF

where PR is the power recorded on spectrum analyzer, in dBm, KA is the test antenna factor in dB/m, KG is the
combined pre-amplifier gain and cable loss in dB, KE is duty correction factor (when applicable) in dB, and CF is
a distance conversion (employed only if limits are specified at alternate distance) in dB. This field strength value is
then compared with the regulatory limit. If effective isotropic radiated power (EIRP) is computed, it is computed as

EIRP (dBm) = E3m (dBµV /m) − 95.2.

4.2.2 Hopping Channel Dwell Time
The average time of occupancy on any hopping channel must not be greater than 0.4 seconds within a 20 second
period for FHSS device with 50 operating channels. For this test, the EUT was set for data transmission with
hopping enabled. Results of this testing are depicted in Table 5. Plots showing example measurements

mode is independent from the packet type (packet length) for all Bluetooth devices. Therefore, Bluetooth devices comply with the dwell
time requirement.

made to obtain these values are provided in Figure 6.

4.2.3 Hopping Sequence and Spectrum Use
It is required that the EUT hop to channel frequencies that are selected at the system hopping rate from a pseudo
randomly ordered list of hopping frequencies. Each frequency must be used equally on the average. In addition,
system receivers are required to have input bandwidths that match the hopping channel bandwidths of their corre-
sponding transmitters and that shift frequencies in synchronization with the transmitted signals. Furthermore, the
system must be designed to comply should the transmitter be presented with a continuous data (or information)
stream. In addition, a system employing short transmission bursts must comply with the definition of a frequency
hopping system and must distribute its transmissions over the minimum number of hopping channels specified in this
section. Finally, the incorporation of intelligence within a frequency hopping spread spectrum system that permits
the system to recognize other users within the spectrum band so that it individually and independently chooses
and adapts its hopsets to avoid hopping on occupied channels is permitted. The coordination of frequency hopping

4.2.6 Channel Separation
For this test, the EUT was enabled for data transmission with hopping. The Carrier Separation was measured for
low, mid, and high channels. Results of these measurements are shown in Table 8.

Pi/4DQPSK
Channel Separation is the same for all modulations in a Bluetooth transceiver. Only worst-case GFSK modulation was tested to
demonstrate compliance.
