The CipherCAD testbed is a unique workplace for the development, design, testing, verification and teaching of the communications systems. CipherCAD is at the core of the workplace, which is an application primarily designed for solving cryptographic tasks. The application can also be used for communicating with hardware communications devices. The workplace is used in the Department of Communications Technologies at the University of Defense. The article will present selected exam-ples used in this workplace. The introduction introduces CipherCAD and the possibilities for creating simple models. The first model to be selected shows how to control SDR IZ225 and process the signals received. The next model shows how selected modulated signals are gener-ated in real time, and their transmission throughout the whole chain of communications. The models that follow show how they can be used in the field of communications protocols, VoIP transfer and changing any of the parameters of the transmitted information.
