Engineer's workbench design. This contains a voltmeter that can measure from 0-4v. An ohm meter that can measure from 100-11000 ohms. A stable DC reference source that outputs 0-4v. A square wave that produces a +/- 5v wave with variable frequency. A sine wave with variable amplitude that varies from 0-1v up to 0-5v with variable frequencies from 1kHz-10kHz.
