DIGITAL OSCILLOSCOPE BASED ON FPGATO USE A BIOMEDICAL RESEARCH

Recently widely used digital oscilloscopes based on personal computers. This oscilloscope consists of a specialized signal acquisition board which can be an external USB port device respect to computer. The user interface and signal processing software runs on the user's personal computer. In this work, digital oscilloscope based on programmable device FPGA only is proposed. The main three units oscilloscope control, data acquisition and VGA controller are fully implemented on the FPGA chip only. The required external units are ADC board and monitor. As result of the project we have designed and implemented the simple digital oscilloscope using PEGASUS FPGA board and AIO1 analog peripheral board from Digilent. The design implements common features of a conventional oscilloscope, such as sampling rate adjustment, hold and triggering.
