The Lynx user guide mentioned a control panel action to calibrate the ADC and DAC channels to null DC offset from thermal drift.That's pretty slick! They must digitally null the inputs and then activate a relay connecting them to the outputs and use them to measure the DC offset. Then, numeric offsets are applied to every data sample going in and out to compensate.
Pictures of the card look fairly good too, with nice LC filtering of the PCI bus +/- 12v power, and regulators for the other voltages.
