Design and Implementation of Intermediate Frequency Generation and Analysis Module for Avionics Test

Abstract

To test airborne avionics device, it is necessary to provide signal stimulus for the device under test (DUT) to simulate the real work environment. This paper proposes a hardware module which used to signal generate and analyze. The hardware structure and diagram of logic design are described. The generated waveforms and measurement results are presented. This test module combined with other necessary modules can achieve the test of L band airborne avionics such as ATC, TCAS and TACAN.
