surajbarkale Posted August 5, 2004 Report Share Posted August 5, 2004 You have to build an attenuator for scaling the input signal. Even then your bandwidth wil be limited to about 20KHz (i.e. AF range). If that is not sufficient, then you have to use a fast ADC with FIFO to store the samples then use Serial/Parallel/USB port to upload data to PC & write a program to analyze & display it! Also u may need a frequency synthesizer to generate various sampling rates such that you can measure a signal without overflowing buffer. you can also take a look at http://www.bitscope.com and analyze their design Quote Link to comment Share on other sites More sharing options...
