I have been using the Analog Discovery for an embedded systems class I recently completed. The regular price is $239 but the student edition is only $99. It’s small enough to fit in your pocket, but powerful enough to replace a stack of lab equipment. It is driven by the free WaveForms software and lets you build and test analog and digital circuits in virtually any environment, in or out of the lab. Here is the link:
2-Channel Waveform Generator
16-Channel Logic Analyzer
16-Channel Digital Pattern Generator
±5VDC Power Supplies
Now supported by MATLAB / MATLAB student edition.
