TX tests
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 Measure and record the TX ON current consumption of the Phone/ flash adaptor.
2 Monitor the WLAN TX spectrum on a Spectrum analyser either using a co-ax cable connected to the WLAN
TX antenna port or by making a radiated test with a suitable WLAN antenna connected to the spectrum
analyser input. (When making a radiated test ensure that other WLAN devices are not transmitting as
these may be detected as well, confusing the result).
3 To finish the test select the Finish option button
4 Measure the TX OFF current consumption of the phone/flash adaptor.
The difference between the two readings should be 110 - 180 mA and measures the transmit current in
11MBPS, 802.11b mode of operation.
