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™ (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 either 2.4GHz or 5GHz (For RS9113
module).
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.

User Guide for Linux
The ‘transmit’ utility is a command line application to perform Tx tests.
Before running the Tx tests, the user is expected to connect RS9113™ 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.
Please follow “RS9113-SW-Installation-Guide” for building and installing
the RS9113™ driver.
To configure the driver in “PER” Mode make sure to have the following
line in “release/insert.sh”.
DRIVER_MODE = 2
After the card has been detected successfully (issue “dmesg –c” in
terminal to check the status for the USB card it will show “new high-
speed USB device detection” while for the SDIO it will show “new High
speed SDIO card detected”) the Tx and Rx tests can be started. Please
follow the subsequent sections for executing the Tx and Rx tests.
When driver is compiled in “host” directory driver would be using binaries
from “release”.
If there are any modifications in “host” directory then driver compilation
is required.
The RS9113 driver offers two main modes of operation:
1. End-end, or Wi-Fi mode
2. PER mode for PHY evaluation
To configure the driver in Wi-Fi or (END-to-END) Mode make sure to have
the following line in “release/insert.sh”.
DRIVER_MODE = 1
In order to configure the driver in PHY Evaluation mode (PER mode) then
make sure the “DRIVER_MODE” parameter should be set as
DRIVER_MODE = 2

We can enable multiple fields by setting rate flags value appropriately.
Set Aggregation flags:
This flag is for enabling or disabling aggregation support .Higher length
packets can be transmitted by enabling aggregation flag.If this flag is set
then it enables the TX aggregation. User can give maximum of length less
than or equal to 30000bytes when the aggregation is enabled. This
maximum supported length may vary depending on the available buffers
in TA. User given length is divided into chunks of size 1792 bytes. All
these chunks are aggregated and sent. If this flag is not set then
aggregation is not enabled and packets will be sent without any
aggregation, And maximum length that can be sent in this case is
1536bytes.
Aggregation feature is supported only in burst mode. This filed will be
ignored in case of continuous mode.
Set Number of packets to send:
This field is used to set the number of packets to be sent in burst mode.
If the value given is ‘n’ then ‘n’ number of packets will be sent on air,
after that transmission will be stopped. If this field is given as ‘zero’ then
packets will be sent continuously until user stops the transmission using
transmit utility.
This filed will be ignored in case of continuous mode.
Set Delay between the packets:
This field is used to set the delay between the packets in burst mode.
Delay should be given in micro seconds. i.e. if the value is given as ‘n’
then a delay of ‘n’ micro seconds will be added for every transmitted
packet in the burst mode.
14
Onebox-Mobile
PHY Evaluation Test Utility
User Guide for Linux
If this field is set to ‘zero’ then packets will be sent continuously without
any delay.
This filed will be ignored in case of continuous mode.
Examples:

4 Programmable PER packet
PER packet can be programmable using utility called ‘transmit_packet’
utility. This utility takes the PER packet content from the file called
‘per_packet.txt’.
‘transmit_packet’ utility and per_packet.txt can be found under ‘release’
directory.
Before running this utility user has to fill the required packet content into
‘per_packet.txt’ file starting from the MAC header. Once ‘per_packet.txt’
is filled user can run ‘transmit_packet’ utility for configuring the PER
packet. This utility configures the PER packet only. It will not start
transmission. User has to run the ‘transmit’ utility as described in the
previous section after running ‘transmit_packet’ utility.
If user does not want to configure the PER packet then ‘transmit’ utility
can be run directly without running ‘transmit_packet’ utility. In this case
default PER packet will be sent.
Configure the following parameters through ‘transmit_packet’ application
before running the ‘transmit’ utility.
Programmable PER Packet Enable
Programmable PER Packet Length
Sequence number flag
4.1 Application Usage
Before running application PER packet content has to be entered into the
‘per_packet.txt’ file.
Then the application can be started in the following manner:
# cd release
# ./transmit_packet <e> <l> <s>
<e> refers to enable or disable flag for PER packet configuration.
<l> refers to length of the packet that has to be configured in bytes.
<s> refers to sequence number flag.
Enable flag:
This flag is used to enable or disable the PER packet configuration.
1- Enable,0 - Disable
If this flag is enabled, newly configured PER packet can be transmitted
when user runs ‘trasmit’ utility.
If this flag is disabled, default PER packet can be transmitted when user
runs ‘trasmit’ utility.
16
Onebox-Mobile
PHY Evaluation Test Utility
User Guide for Linux
Length:
This field refers to the number of bytes to be configured from the
‘per_packet.txt’ file into PER packet. i.e if this field is given as
‘n’(maximum value of n is 1536bytes), then ‘n’ number of bytes can be
configured from ‘per_packet.txt’ file into PER packet.
Maximum allowed value for this field is 1536bytes.i.e PER packet can be
programmable upto 1536 bytes only.
Sequence number Flag:
This flag is used to enable or disable the sequence number from the
‘per_packet.txt’ file.
If this flag is set as ‘1’ then it will take the sequence number from the
‘per_packet.txt’ file. And each transmitted packet contains same
sequence number without any increment.
If this flag is set as ‘0’ then it ignores the sequence number value from
‘per_packet.txt’ file and sequence number will be incremented starting
from ‘0’.
Default value for this flag is ‘0’.
If the Length filed in ‘transmit_packet’ utility is given as ‘m’ and Packet
length in ‘transmit’ utility is given as ‘n’
Then
1.If m<n then, first ‘m’ bytes can be taken from ‘per_packet.txt’ file into
PER packet and the rest of packet (m-n length) contains default content.
2.If m>n then, ‘n’ bytes can be taken from ‘per_packet.txt’ file into PER
packet and transmitted.
3.If m=n then, ‘m’ bytes can be taken from ‘per_packet.txt’ file into PER
packet and transmitted.
User has to take care while filling per_packet.txt. i.e content should be in
hex format only.

Above command configures the PER packet
PER configuration Enable – 1
Length – 500 (500 bytes can be configured from the ‘per_packet.txt’ file)
Sequence number flag – 1 (Sequence number will not be incremented)
After starting this application, user has to enter the following command to
stop the ongoing transmission:
$ ./transmit_packet 0
Above command disables the PER packet configuration.i.e default PER
packet will be sent when user runs ‘transmit’ utility.

5 Receive Tests
The receive tests can be invoked from an application called ‘receive’
which is found under ‘release’ directory. Use this application for displaying
the following information
Total number of CRC PASS packets
Total number of CRC FAIL packets and
Total number of FALSE CCA
5.1 Application Usage
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.
PER: Packet Error Ratio (PER) is calculated by measuring the number of
packets received correctly and comparing with the number of packets
expected.
%Packet error rate = 100*(1- ((Received packets/expected packets))
For carrying out the receive test, connect the EVB to a Vector Signal
Generator (VSG). Then set the RF amplitude, signal waveform and the
channel in the signal generator before starting the receive tests.
You need to configure the channel (as mentioned below) in the EVB with
the same channel which is set in Signal Generator.
The application can be started as follows to start receiving the packets
from EVB. Go to ‘release’ folder.
$ ./receive <file> <channel number> <start - stop>
<channel width>
<file> is the name of the file into which the above information will be
written. In addition, you can see this information on the console.
<channel number> is the channel number on which receive tests are to
be done. For 2.4GHz channels, please refer table 1 and for 5GHz
channels, please refer table 2.
<start – stop value> is to either start or stop receive application. To
start set this value to ‘0’ and ‘1’ to stop receive application.
<channel width> is the value of the operating bandwidth of the
channel. Channel width values are specified in the following table.
