Why Use Test Signal Generation and Analysis
Accelerate optical communications research.
Transitioning photonic designs from simulation to laboratory validation can be complex and time-consuming. This solution bridges that gap by seamlessly connecting simulation environments with real-world test equipment, enabling engineers and researchers to efficiently validate, analyze, and optimize optical communication systems. Advanced signal processing and measurement capabilities support critical analyses such as BER, EVM, constellation diagrams, SNR, and CNR, helping teams gain deeper insight into system performance. Automated data transfer, signal conversion, and equipment integration reduce manual effort while improving repeatability and accuracy. By combining simulation-driven design methodologies with laboratory verification workflows, users can accelerate research, shorten development cycles, reduce testing costs, and bring innovative photonic technologies to market faster.
