Agilent has oscilloscopes to 63 GHz /160GS/s. How is that possible?

Using Arduino General Electronics

You can make a 100GSample/sec oscilloscope with arduino as well:

  1. sync the signal at point A
  2. take a S/H sample at t=A+10ps, ADC and store data (d1)

Ya got me there. I never could get step 2 to work on the PIC. Darn, should have
tried the Arduino .
