RE: diy oscilloscope 2009/06/12 16:44:08 -2 (1) If you are looking to make a hobbiest scope of something a magnitude better than 10KHz, I would recommend going to an off the shelf technology beyond microchip (though I would love to see mC pick this one up); Look at using an FPGA (something any E-hobbiest will likely enjoy), and just to keep the ...
Oscilloscope Art with the Xilinx Zynq FPGA (Zedboard) Watch the Zedboard drawing pictures on an analog oscilloscope while producing sounds.
The input of each T flip-flops is set to 1 to produce a toggle at each cycle of the clock input. For each two toggles of the first cell, a toggle is produced in the second cell, so its output is at half the frequency of the first. The output of the third cell is 1/8 the clock frequency. The same device is useful as a counter.

With respect to the current technology, they were bulky, expensive, and consumed a great amount power. The digital revolution changed all that. The design of a digital oscilloscope is centered around an analog to digital converter. Once the signal is digitized, it is processed by an FPGA or a microprocessor before being displayed.
Sometimes an oscilloscope is a must. I can't live without one. Since you want to develop with FPGA I don't think you find a logic analyzer very useful. There are very good Internal Logic Analyzers for FPGA. I mostly use this internal logic analyzer from FPGA Cores. This require that you have your board connected to a network.
