I have question about visual analog.
My board is ad9613-250ebz and hsc-adc-evalcz
1. I used function generator (V peak 2.8V with 50MHZ ) for input. I programmed the virtex4 fpga based on "fifo 4-5 interposer" which I modified with 1 channel(when I was trying to do that, pin g15 the usb ifclk got an error for using diffrent clk)
and I used visual analog, none of the data(there was just one line at 0).
2. So I tried to default, with the visual analog. But when I did the default, the done led on. But at this time, visual analog shows nothing on fft graph.
3. So I wonder, if I change fpga at least once, can't I use visual analog for fft?
