Digital Electronics Lab

The DL7211 is designed for experimentation with digital circuits. It is a self-contained trainer including DC power supplies, function generator, modulation generator, continuity tester, potentiometers and toggle switches. A breadboard is supplied with the unit to allow easy access for the students to connect and test various components without the hassle of soldering. A number of ready to use experiment circuit boards are available and fourteen boards are provided with the lab.
