There are many examples of electronics trainers on the market. All share two things in common: they are expensive, and do not offer a built-in oscilloscope and other test equipment. Oscilloscopes are invaluable tools for performing electronics work, and most are just too expensive for the hobbyist/student to purchase. The Spectral Display is a useful and unique feature as well. Our analog trainer offers all of the above features, including a function generator with a white noise source and power supply,and will retail for around $250 (less if the volumes are high enough).
