HANBACK ELECTRONICS CO., LTD. is a Korea company developing and providing FPGA, DSP, Optical Communication and Electricity and magnetism practice equipments.HBE-DTK-240 allows user operate hardware designed by users themselves using FPGA widely used in industry. Experiments with HBE-DTK-240 not only let users experience what can not be learned from textbooks only but also allows students to get interested in digital circuits.DSPLAB2000 is an experimental kit for those using experience signal process for the first time. It provides diverse examples so that users can master signal process concepts faster and more easily. When mastered, users can experiment programming signal processes in various other ways as they desire. It is also built to expand hardware easily with separate control line and address data line.HBE-OPT-303, a fiber optic communication test equipment, is the best experimental equipment that can be used by from beginners to experts. All the experiments can be done in this equipment without high priced fiber optic test equipments since this equipment has 2 channel functionalities movement digital oscilloscope and optic power meter that can test physical features and response principle of optical communication elements, refraction, total reflection, noise, and loss. HBE-OPT-303 can be controlled by a dedicated software with a optimized PC interface, not by a hardware.HBE-EMPOS II is an experimental equipment, utilizing Intel Xscale core, that provides a wide development environment for Internet application products; it is built to be compatible with Internet application development with 128MB memory. HBE-EMPOS is Linux-loaded. Sources and examples are also included to help users become more familiar with the unit.
