Testing the units
Test the units to make sure that a basic RF link exists and data can be sent over it. In this section you
will complete the following tasks.
A) Test the link with Linktest
B) Perform some simple network tests
Testing the RF link with Linktest
In this step, you will test the basic RF link with Linktest. Linktest verifies that a link can send and
receive test data.
➧
To test the RF link with Linktest
NOTE:In a lab environment the units are physically closely located. In order to avoid saturating the
receivers make sure that the power setting is low enough.
1. Connect a PC to the serial port of the Libra Unit and access the Main System Menu.
2. Log in using the supervisor password.
3. Press
Esc
until the

command line prompt appears.
4. From the

prompt type the following command.

. If the RF link has been configured properly the Linktest results appear.
station
ID
RF Station ID of the Linktest remote unit. This can be the base station of the
system if Linktest is run from another BWS unit.
acc
Accuracy of the test, expressed as 1E<acc> bits. The default is 6 (1E6), or one
million bits. The acc value defines the number of bits sent for each line of
displayed statistics. Sending more bits makes the statistics more accurate, but
takes longer. The test sends 10 times the acc value. Choosing an acc value of 6
(one part in a million) causes the test to send 1E7 (10 million) bits.
pps
Transmission speed in packets per second (pps). The default is 60 packets per
second. The lower the pps, the less bandwidth the Linktest takes up, and the less
it affects any message data being sent at the same time. A higher pps value
speeds up the test.
