Description

Far Field monitor system

The LTR 400 FF is a special variant of the LTR 400 transponder system. The LTR 400 Farfield Monitor is a transponder installed at a fix position and operated for test and monitoring purposes for an interrogation system.

The transponder replies to interrogation calls. 
The reply signal can be evaluated and interpreted within the interrogator.

The LTR 400 FF system is available with different variants of LTR 400 transponders to fit perfectly to customer needs.

The LTR 400 FF system is either provided with a fixed altitude setting of 99.000 ft. that can be selected through the remote Control and Display Unit (CADU)  or with a Gilham Dongle, which can be plugged  into the CADU Gilham interface to set the required fixed altitude.

To support full Mode 5 Level 2 functionality cables delivered within the LTR 400-CFF System are equipped with ARINC 429 break-outs that can be used for provision of required navigation data to the LTR 400.
