TS4000 Radio Modem User’s Manual Testing 40
Testing
The TS4000 configuration program is provided with AirTest, Teledesign’s general
purpose wireless modem test software. AirTest can send data and gather
performance statistics about the link between two modems.
To start AirTest press the AirTest button on the main screen of the configuration
program. For details on using AirTest consult AirTest’s on line help.
To test the operation of the TS4000, AirTest can be used to pass data between
two modems.
1) Attach two TS4000s each to a PC serial port.
2) Setup AirTest for the correct serial port baud rate, data bits and parity
(matches the TS4000’s setting).
3) Transmit data between the TS4000s by typing a message into the Tx
Message box of the Comm Port window followed by the ENTER key.
4) Automated tests can be run that will send data and verify that it is received
correctly. To select a test, use the Test Setup command from the Setup
menu. Use the on line help to obtain more information about each test.
A BER (Bit Error Rate) test is used to determine how good a radio environment is
for transmitting data. The BER result tells the percentage of bits that are
corrupted. A BER of 3.0 x 10
-4
means that 3 out of 10,000 (10
4
) bits are
corrupted.
