Figure 1: Linux Based RF Evaluation Setup With RJ45 Interface
Following diagram illustrates various software components involved in performing Tx
and Rx tests using spectrum analyzer and signal generator respectively.
The ‘transmit ’ utility is a command line application to perform Tx tests. Before
running the Tx tests, the user is expected to connect ALXC28 moudle to a signal
analyzer using the RF cable.
The ‘receive ’ utility is also a separate command line application that can be used for
displaying statistics on the received packets while carrying out the receive sensitivity
tests.
3. Application Usage
In general, before performing any tests configure the PHY to operate in the
appropriate band. The transmit tests can be performed through a utility called
‘bcmdhd_active.sh ’ which is found under ‘wifi’ directory .
Configure the following parameters through this application before running the tests.
Transmit power
Transmit data rate
Transmit mode
Channel number
