Comprehensive Learning in One Device

This trainer offers a practical approach to learning the essentials of Pulse Code Modulation and Time Division Multiplexing. With two analog input channels and selectable sampling frequencies, users can conduct a range of experiments vital to modern communication systems. Its combination of PCM encoding and TDM output, clearly presented on the front panel, makes complex concepts accessible and easy to visualize.


High Accuracy and User-Friendly Design

Engineered for precision, the trainer generates pulse code modulation signals within a 1% tolerance. All components are securely housed in a rigid MS cabinet with a quality PCB, ensuring durability and long service life. The intuitive layout, LED indicators, and labeled test points streamline user operations, making the device ideal for instructional and laboratory settings.
