PHY Evaluation Test Utility
User Guide for Linux
1 Introduction
The purpose of this document is to provide the usage of the applications
for transmit and receive tests to evaluate the RF performance of the
RS9113™ using a test driver in Linux environment.
The evaluation board provides the necessary connectors so that you can
measure transmit and receive performance of the PHY, using Spectrum
Analyzer and Signal Generator in 2.4GHz.
In general, transmit performance of a radio can be analyzed in three
steps.
Maximum power: The user can observe the RF output power for a given
maximum gain supported by the RF.
EVM: The user can observe the EVM for a given rated RF power as
supported by the RF transceiver.
Spectral Mask: The user can verify whether the RS9113™ module meets
the spectral mask requirements defined by IEEE standard for a given
maximum RF output power, in a particular mode of operation like 11a,
11b, 11g etc.
The receive performance of the PHY can be analyzed using Packet Error
Ratio (PER) test.
The Rx performance is analyzed by the sensitivities at different data
rates. In general, the sensitivity is observed as 10% Packet Error Ratio
(PER) point in 11a and 11g, and 8% PER point in 11b.
The document contains two major sections.
Section 3 describes the usage of the ‘transmit’ utility, which provides the
options for setting various parameters to carry out transmit tests on the
RS9113™ device.
Section 4 describes the usage of the ‘receive’ utility, which enables the
user to perform receive tests on the RS9113™ device.

2 Test Setup Details
The diagram shown below, illustrates the test setup for evaluating receive
and transmit performance of RS9113™ WLAN module.
As shown in the test setup, the RS9113™ evaluation board (EVB) is
plugged into Linux based laptop either on the SDIO slot via SDIO
connector or USB port via USB cable through port J6 on the EVB. The
board is connected to a WLAN signal analyzer through a microwave
coaxial cable to test the Tx performance.
