The Chameleon SA is the industry’s first stand-alone CoaXPress v2.1 Camera Simulator. This simulator is capable of generating video streams and test patterns of up to 4 CoaXPress v2.1 links in single, dual, and quad modes. Each link supports standard CoaXPress v2.1 bitrates up to 12.5 Gbps. This product is ideally suited for the development of industrial, defense, and aerospace Machine Vision Systems and applications. The Chameleon can easily transmit generic test patterns, customer’s specific pre-processed data, or custom video streams on the CoaXPress v2.1 links. It also provides GPIO for machine control signals, such as triggers, shaft encoders, exposure control, and general I/O, which can be simulated together with the video streams. The simulator enables transmitting the video streams from onboard memory as well as run time uploading the streams from computer memory.
The Chameleon uses Micro-BNC connectors for CoaXPress links as an interface to the Frame Grabber board and standard headers for general-purpose I/O. The Simulator utilizes Thunderbolt 3 interface for communication with Host PC for video uploading and configuration.
