The PCB came in and I have assembled it. The preliminary look at the transfer function on the AG4395A shows that there is a problem. The function is very noisy and the signal is very low. I will go through and verify all the solder points are fully connected and generally debug the circuit. A quick measurement of the transfer function on the SR785 of the low frequency (10Hz-100kHz) showed good results earlier so I fear something has come loose. Note the low-fq measurement was not recorded properly. so I have no graph for it. 

I think this is a small fix that needs to be made. 

The graphs below show the EOM and PZT path TF measurements on the AG4395A. They make it clear that something is not connected. This is just a progress report.
