Design Of Virtual Instrument

During the teaching process of electronic science and technology,oscilloscope,wave generator and spectrum analyzer play important roles.But,many traditional electronic instruments are very heavy and not easy for students to take away and all these instruments have high price which can't be afforded by students.So they can't meet the needs of student's daily experiment requirement.So we design a cheap virtual instrument which contains the function of high price oscilloscope and wave generator.During the design,we will replace the high ratio screen with USB Cable.Users can control the program running on computer or mobile to see the result and control the system.The design will decrease the cost of instrument which can help students finish daily experiments in their own dormitory,help them make full use of time to improve themselves.The system design will include wave generation circuit,high speed sampling circuit,the core controller circuit based on FPGA,ARM SRAM,and usb transfer circuit.The software design will contain high speed sampling program based on verilog,the data transfer and controller program based on C language,and the human-computer interaction program based on Qt and Android.
