F1 Transponder Testing
The Transponder Testing function allows the operator to verify the operation of all industry
standard beacons in air. The system measures Turnaround Time (TAT), Pulse Width (PW) and
Reply Frequency (mode dependant) using the 3102 Test Transducer.
Select the desired configuration to test the beacons operation.
The 3102 test transducer should be connected to the front panel test transducer socket. To test
the responder function the CHA-1082-4000
lead should be connected to the beacon serial port on
the front panel and the connected to the beacon.
The turnaround time (TAT) is the time it takes for the beacon to respond to an interrogate signal.
This time depends on the type of beacon and how far the beacon is away from the test transducer.
The pulse width is the length of the transmitter pulse. This value can vary due to the beacon type.
If the PAM indicates a pulse width significantly longer or shorter than expected then the beacon
may be faulty.
The final parameter which is tested is the beacon reply frequency. The PAM will calculate the
frequency of the receive signal and display the results. If the frequency is out of the expected band
then it will display an error message as well as the received frequency.
