Thanks Alex,

Now there is a question about type of input signal. As there is a RF transformer after the input of AD card, What kind of input can I have? Currently I am trying to input a 2V DC input. but the input (SMA input terminal) is shorted. I mean there is no place for ground. My final goal is to input 100 Hz square waveform with duty cycle of only 80 ns. I have attached the AD card input schematic and my desired project with AD and FPGA.

I have an input signal as 2V amplitude, 80 ns, 100 Hz and want to convert it by ADC to digital then I can limit/modify the bites (the input).

Please have a quick look at it and let me know your instructions.
