Digital oscilloscope A digital oscilloscope has many advantages over its analog counterpart, like the ability to capture single events, and to display what happens before the trigger. You can build a digital oscilloscope simply by hooking an ADC and an FPGA together. This particular design uses an 100MHz flash ADC, so we are building an 100MSPS (mega-samples-per-seconds) oscilloscope. This oscilloscope design is interesting because it shows how powerful and useful modern FPGAs can be.
HDL design Or how to create the oscilloscope logic inside the FPGA. Hardware This design was created using the Flashy boards.See also the "hands-on" page on how to build a simple oscilloscope. Software Screenshot Here's the view of a 27MHz signal, sampled at 100MHz and reconstructed using the "sample equivalent time" technique. Links.
