Hi all,
I have always wanted to have an oscilloscope for my hobby but the professional ones are quite expensive ($$$$) and while I have found a few construction most of them are toys - like "connect and ADC to the parallel port of the PC & so on ...)
A few days ago I have received samples from National (ADC08060) which is 60 MSPS 8-bit ADC - should give frequency response 20-30 MHz. But of course, a common MCU (PIC... etc) cannot read the data from the ADC fast enough. I am thinking about using a FPGA - luckily I have 2 FPGA boards (XSA3S1000 from XESS and Spartan-3E starter kit from Digilent, Inc.) Then I think I can interface the FPGA to a MCU and then PC (serial or better USB).
I am wondering if someone already did something similar (or is planning to do)
I was thinking about using even faster ADCs - they are available from National or other companies but the challenge is to read the data fast enough from those chips and store them in RAM...
