Portable Digital Electronics Circuit Trainer


• It adopts a portable box type design with an aluminum profile frame, easy to be carried for flexible teaching purposes.

• This trainer is a classic digital circuit training system, which is suitable for experiment teaching courses such as ‘Digital electronics technique’ and ‘Electronic circuit’.

• The basic service area comes with DC power source, single pulse, fixed pulse source, logic level input,
indicators, nixie tube display, dial switch, etc. The open experiment area is provided with multiple IC sockets and electronic component insertion sockets to achieve various experiment extension and course design.
