[Matteo, Eleonora]
Last Friday we have modified the 500MHz oscillator (realized by Pierre) to make it provide two more channels (four in total).
We have simply replaced the two channel splitter inside (pic1) with a four channel splitter (pic 2-3) and modified the front pannel accordingly (pic4).
Now we can supply the 500MHz clock signal to all the three DDS boards we have.
