The EE-4000 Digital Electronics Trainers is a series of 10 Experiment Circuits Modules designed to fit our ULT-3000 Universal Lab Trainer (Analog and Digital Lab Trainer) in place of the standard breadboard module. Each experiment circuit schematic is clearly printed on the top panels of the modules.

This trainer complete with needed power supplies and source generators needed to carry out the digital electronic experiments complete system with connecting leads, experimental and teacher manuals.

An experiment manual accompanies the modules detailing eighteen (18) experiments in an easy to follow step-by-step manner. These benefit the student in that valuable lab time can now be devoted to studying the Digital Electronics.

Main Unit ULT-3000

The main unit incorporates all necessary equipment for use with the plug-on training modules. Power supply, signal generator, and a wide range of logic switches and indicators are all built-in.

The DC power supply provides fixed ±5V at 1A, ±12V at 1A, and a variable ±1.5V~±20V at 1A The function generator & signal generator provides clock signals from 1Hz to 1MHz in 6 ranges. The main unit is also supplied with a removable 1680 tie point universal breadboard for general experimentation and prototyping circuits rather than wiring them up.
