Oscilloscope assembly part2 + FPGA JTAG

I have almost finished to assemble channel 1 of the oscilloscope.
so far everything seems working!

I connected the Xilinx's USB programmer to the JTAG chain of the FPGA ad Impact sees the FPGA:

That is a very good news! I can now program the FPGA and start doing basic testing like switch the AC DC relays...control the attenuation, gain, etc.
I'm still waiting an op amp from RS which is supposed arrive tomorrow.
if everything goes well, next weekend I should be able to start to test the input amp. stage!
