keyword=Ramp Delay change. Sync checkIt appears that the timing board in the Right Spectrometer has it's LSB stuck... and is creating a Ramp Delay of 2.5us. This would explain my previous halog entry (125257). To test this... I changed the ramp delay to 1 for the Counting House, Injector and Left Spectrometer timing boards... and kept the ramp delay of 0 in the Right Spectrometer timing board for run number 2011. The plot below shows that everything is back in sync. Hopefully, during an access, I can verify this on a scope. I can then just replace the Right Arm timing board with another (which I have verified to be OK).
