50Hz brought by network analyzer

Pierre, Aritomi and Yuhang

We found that when we just connect the source port of network analyzer to servo, the error signal presents a very very large 50Hz noise.

Check the power supply of the network analyzer connection. To avoid ground loops it should be connected to the same power line of the rack.

When I connect it with the same power with rack, the 50Hz noise becomes even higher!

Another thing to be noticed is that when I use SR560 as servo, and inject noise from network analyzer to SR560, there is no 50Hz noise!
