Carrier ID Reception System Data Acquisition based on ZODIAC DATA SYSTEMS IFoIP Technology Spectrum Visualization and Analysis based on ZODIAC DATA SYSTEMS CSA system Carrier ID detection and demodulation performed on ZODIAC DATA SYSTEMS CID Analysis

System Search Range to Frequency Offset set to 10kHz (adds 10s to GUID detection speed compared 1kHz search range) Full Analysis enabled:

• Looks for up to two different carrier ID around the same center frequency and within the same frequency search • Tries to decode the full Carrier ID message • Carrier ID Detection : Simple mode, with fallback to Deep Detection mode (requiring more processing) in case of

detection failure


Carrier at nominal power, three

tests performed in: QPSK / 8PSK / 16APSK No identified difference in

processing capabilities
