Subject: PLL noise and beat frequency at 50MHz 

Summary

Today the beat frequency was very difficult to find. Something changed, and I am not sure yet how to drive

the frequency of the beat. However the beat frequency is at 50MHz while so far it was at 64MHz. The PLL lock

more difficult and noisier.

 

Note:

Sometimes today or Yesterday we have increased the temperature of the lab (~ 2 degrees F).
