In summary these two Self tests provide a simple means of ensuring the Host engine is able to communicate
with the WLAN module and check the interface to BTH. More detailed WLAN performance test is covered in
WLAN functional test section.
WLAN functional tests
On/Off test
Prerequisites
A flash adapter connected to a PC with Phoenix service software is required.
From the testing toolbar select WLAN Configuration option. This opens the WLAN configuration dialogue
box below. Selecting the Power state option button (as indicated), the WLAN can be turned ON and OFF:
1 With Power State set to OFF, measure the dc power supply current consumption of the flash adaptor.
2 Next return the Power state to ON and re-measure the dc power supply current of the flash adaptor.
The difference between the currents in (1) and (2) should be between 190 to 220mA. When WLAN is ON, the
firmware has been downloaded and the WLAN module is in the receive state. When OFF WLAN is powered
down.
TX tests
Prerequisites
Connect complete phone assembly with C-cover to a PC with Phoenix service software using a USB data cable.
From the testing toolbar select WLAN Tx Test option shown below. This test can be used to verify TX
configuration and functionality. The default settings are sufficient for testing the TX operation, although
other channels and data rates are equally suitable. To start the test, select the Start option button:
1 Monitor the WLAN TX spectrum on a Spectrum analyser. (When making a radiated test ensure that other
WLAN devices are not transmitting as these may be detected as well, confusing the result). A typical
11MBPS TX spectrum is shown in figure below.
