Description: 实现函数发生器产生的波形能够在电脑显示器上显示。函数发生器通过GPIB卡与电脑连接并传输数据,电脑上通过LABVIEW软件环境完成与GPIB卡的数据通信。在LABVIEW环境下完成了对虚拟仪器前面板以及后台程序框图的设计与编程。在LABVIEW开发环境下,实现对GPIB控制时,采用VISA模块驱动的方法进行编程。设计结果在LABVIEW环境下的虚拟示波器能够实现示波器的功能,能够显示函数发生器所产生的任意波形。- achieve the waveform can be displayed on the screen of the computer which send out by the function generator. The function generator connect to computer through a GPIB card and transfer data. Labview can be communicated with GPIB card and save data on computer. The virtual instrument front panel design and background process diagram programming can achieved under Labview software environment. The realization of GPIB control, using VISA module-driven approach to program in Labview. The result of the design is that the virtual oscilloscope is able to complete the Real oscilloscope function in Labview. Platform: |

Description: 1.采用Labview设计一虚拟函数信号发生器, 通过数据采集卡输出波形信号,调节信号的相关参数,可观察示波器上波形的变化情况。
⑴ 以NI MyDAQ数据采集卡作为输出接口;
⑵ 数据采集卡输出多种信号,至少完成三种波形:正弦波、三角波、方波(可调占空比)的输出,同时前面板上显示各输出波形;
⑶ 频率、幅值、初相位、直流偏移量和方波的占空比(0~100 )等参数可以通过前面板控件调节。
⑷ 前面板可显示输出波形。-1. Labview design using a virtual function signal generator, data acquisition card output waveform signal, adjust the relevant parameters of the signal can be observed on an oscilloscope waveform changes.
⑴ with NI MyDAQ data acquisition card as output interface
⑵ data acquisition card output a variety of signals, to complete at least three waveforms: sine wave output, triangle wave, square wave (adjustable duty cycle), while each of the output waveform is displayed on the front panel
⑶ frequency, amplitude, initial phase, the DC offset and duty cycle square wave (0 to 100 ) and other parameters via the front panel controls to adjust.
⑷ output waveform can be displayed on the front panel. Platform: |
