Research on Application of FPGA in Digital Oscilloscope

With field programmable gate array EP1C6Q240 from Altera as the core device, the research on the application of FPGA in digital oscilloscope was carried out. Making full use of FPGA internal customizable macro function modules and other rich resources to integrate clock divider circuit, latch and data caching circuit of the digital oscilloscope on a FPGA chip was set up. Given system diagram and each functional module circuit implemented by FPGA implementation, QuartusⅡ9.0 was used to design, compile and simulate each module. Tests showed that the system can accurately measure a variety of signal waveforms, operate reliably, and can effectively reduce the cost of the system.
