7.5.9 Verification
In order to verify the correct operation as an RF modem a basic functional
test can be carried out by sending data between the TB7100 base station and
a TM8000 mobile radio.
The following equipment will be required:
■ DC power supply
■ antenna for receiver input
■ dummy load for transmitter output
■ a PC running the terminal application connected to the serial data port
on the base station with a 9-pin serial cable
■ a second PC running the terminal application connected to a TM8000
mobile radio which has been programmed to send and receive the
required data modulation (FFSK or THSD).
The test setup is shown in “RF modem test setup” on page 101.
