The offset could be a problem with the AI chassis. Attachment 1 is a ~3 Hz sine measured directly from the DAC, and attachment 2 is after the AI chassis. There might be a minor offset from the DAC (at most 6 mV), but there is a ~1 V offset after the anti-imaging.

I removed the chassis, haven't done anything inside.
