Integrated Instrument Based on SOPC

Abstract:

This instrument based on SOPC technology is embedded with a NIOS soft-core in Cyclone III as a control center that integrates digital oscilloscope, DDS signal generator and a simple digital multi-meter. It can measure AC signal of 200 Hz-5MHz and 10mVpp-10Vpp, display and store the wave, and can also manually and automatically adjust the amplitude and frequency. This instrument can generate sine wave of 10Hz to 1.5MHz, square wave of 10Hz to 200 KHz, triangle wave, and saw-tooth wave vary from 150mVpp to 10Vpp. Also, it can measure AC and DC voltage of 20mV to 200V, the AC and DC current of 2mA to 1A, resistance of 20Ω to 2MΩ, maintaining 5% accuracy. It is simple, easy to use, can fulfill the general experiment requirements with good performance and strong practicability.
