ADS-B/A/C Signal Analog Generator
1 Device Overview
ADS-B SimulatorThe generator consists of transmitter and host computer software, the reference DO-260B and D0-181E protocol standard simulation to produce four-channel ADS-B signal and A/C signal. Through the upper computer software configuration of each channel unit time to simulate the aircraft batch, transmission power, emission frequency, message information and other signal parameters, as well as the configuration of a specific batch of ADS-B between the channels, and finally through four RF channels synthesis, the formation of a specific degree of interweaving of the 5th channel Signal, Other channels can also be output separately.
2 Device Features
The signal analog generator has the following functions:
1) analog generation of four-channel signal, and signal power, signal frequency, emission rate adjustable;
2) Each channel has a launchADS-B/AIS Beidou Short Message, Mode A/C message ability, and the transmission signal type can be adjusted;
3) can produce up to four-fold interwoven signal, and the degree of overlap can be adjusted;
4) The analog generated signal can be displayed on the map in real time.
3 Main Technical indicators
The technical specifications of the analog signal generator are shown in table 1.
