5.1 Transmitter Requirements

5.1.1 Equivalent isotropic radiated power

Test requirement: EN 300 328 clause 4.3.1

Test Method: EN 300 328 clause 5.7.2

EUT Operation:

Ambient: Temp.: 25.0 °C Humid.: 50 % Press.: 1015 mbar

Status: Keep the EUT in transmitting mode at low channel, middle channel and high channel.

Equipment Used: Refer to section 7

Test procedure: Using the CSR bluesuite software to set up the lowest channel (2402MHz),

the middle channel (2441MHz),the Highest channel (2480MHz).

Test EUT in normal conditions, then repeat in extreme conditions

Limit: 20dBm

Test Procedure:

The technique used to find the output power of the transmitter was the antenna substitution method.

Substitution method was performed to determine the actual EIRP emission levels of the EUT.

The following test procedure as below:

1. The EUT was powered ON and placed on a table in the chamber. The antenna of the transmitter was

extended to its maximum length.

2. The disturbance of the transmitter was maximized on the test receiver display by raising and lowering the

receive antenna and by rotating the turntable. After the fundamental emission was maximized, a field

strength measurement was made.

3. Steps 1 and 2 were performed with the EUT and the receive antenna in both vertical and horizontal

polarization.

4. The transmitter was then removed and replaced with another antenna. The center of the antenna was

approximately at the same location as the center of the transmitter.

5. A signal at the disturbance was fed to the substitution antenna by means of a non-radiating cable. With

both the substitution and the receive antennas horizontally polarized, the receive antenna was raised and

lowered to obtain a maximum reading at the test receiver. The level of the signal generator was adjusted

until the measured field strength level in step 2 is obtained for this set of conditions.

6. The output power into the substitution antenna was then measured.

7. Steps 5 and 6 were repeated with both antennas polarized.

Remark:

None of the spurious emission is exceed the level of 6dB below the applicable limit when tested with resolution bandwidth is 100 KHz.

According to clause 5.7.5, wideband emission is unnecessary.




5.2 Receiver Requirements

5.2.1 Spurious Radiations


EUT Operation:


Status: Keep the EUT in receiving mode at low channel, middle channel and high channel, 1.5m high above groundplane.

Test Limit :

Test Procedure: 1>. Using the CSR bluesuite software to set up the lowest channel

(2402MHz),the middle channel (2441MHz),the Highest channel (2480MHz)

2>.Scan from 25MHz to 12.75GHz, find the maximum radiation frequency to measure.


Test Procedure:

The technique used to find the Spurious Emissions of the transmitter was the antenna substitution method.

Substitution method was performed to determine the actual ERP emission levels of the EUT.








polarization.



5. A signal at the disturbance was fed to the substitution antenna by means of a non-radiating cable. With both

the substitution and the receive antennas horizontally polarized, the receive antenna was raised and
