All 7 OFIS at Elliot are now working without any low frequency oscillations by running each OFIS to a separate Hanada Rack. There is still a little 156 KHz around 50 mV bleeding through on the y-axis for a couple so that is the next issue although Kris was there and didn't think that is an immediate concern. The remaining Y axis oscillations was eliminated by removing the right oscillator module in each HR.

The problems are multifold but mainly the oscillator module with the LT1010 driver and now the 156 KHz on the backplane. When there is time, the next step will be to get both the 156 KHz and the detector signal off the backplane which may or may not also solve the crosstalk between the two sides.
