The PowerSig Mini is a compact power supply and signal generator in one device. This device contains an adjustable DC voltage regulator and an adjustable square wave generator feature. The voltage and square wave period are adjustable by the user. The built in local display will show relevant information to the user. The device can output a max limit of 20VDC(+-5%). The device's square wave output frequency has a range of 60Hz to 2KHz. Engineering Requirements: 1) The system shall be no bigger than 150 cubic inches. 2) The system's output shall not exceed 3 Amps(+- 5%). 3) The system's output shall not exceed 20 VDC(+- 5%). 4) The system's output's square wave shall at least have a 10ms period. Engineering Requirements Results: 1) Met Requirement 2) Did Not Meet Requirement 3) Met Requirement 4) Met Requirement
