I looked into cross talk in the PEM Endevco boards and the Anti-Aliasing boards.  For the Anti-Aliasing boards I directly injected a 5 Hz ramp signal and looked at 10Hz right before saturation. For the Endevco I installed an accelerometer on a shaker at 5 Hz and gradually increased it until just before saturation. The cross talk attenuations in the attached table are at 10 Hz.
