TX tests
Prerequisites
Connect a 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 Tests option as 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, press the Start 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 11
Mbps TX spectrum is shown in the figure below.
2 To finish the test, Press the Finish button.
The difference between the two readings should be approximately 150 mA and measures the transmit current
in 11 Mbps, 802.11b mode of operation.
