Test Mode Application
The Test Mode application allows users to test the RF performance of the transceiver for basic transmitter
and receiver tests. The test mode application is a collection of test modes consisting of the following tests:
•
Idle
•
Transmission 9th Order Binary Polynomial (PRBS9)
•
Reception
•
Link Quality Indication
•
Transmission with modulation
•
Transmission without modulation

Selecting the Transmit Mode
Figure 3-8
shows the Transmit Test Mode option that allows users to display the current transmit test mode
and all the possible tests. To select a test mode, press the appropriate key (S, M, U or P).
Figure 3-8. Transmission Test Mode Menu
To test the receiver, the TX board must continuously transmit a packet on the same channel that the RX
application is running. The message received while in receive mode is displayed in the Hyper Terminal
window as shown in
Figure 3-9
. In this case, the TX board was transmitting the pulse pseudo random
binary sequence.
