 Here is the basic hardware description: [[https://casper.berkeley.edu/wiki/ADC2x1000-8]]
+====The 2GHz clock====
+I was able pr procure a $35 ADF4351_PLL board, from China, and control it with my Raspberry Pi. Here is a picture of the board tuned to 2GHz. This will be used for the clock input of the ADC board. This requires a 10MHz reference signal.
+The controller program is at [[https://github.com/F5OEO/rpidatv]], called adf4351
+To tune it to 2GHz: "./adf4351 2000.0 10000000"
